Thomas Prescher

Located on Lake Biel’s shores, picturesque Twann lies nestled at the foot of steeply terraced  hillside vineyards. This scenic area of Switzerland has not only been home to winemaking for centuries, but also various small and highly specialized watch manufacturers. The solitude and atmosphere of tradition surrounding the town, the natural beauty of its waterfalls and forest, made it an ideal location for the founding of Thomas Prescher Haute Horlogerie in 2002.

Thomas Prescher’s passion for horology born of a childhood obsession with collecting crystals and minerals. As a teenager on a visit to a local jewellery shop, his eye drifted to the watchmaker working at his bench and he was smitten. He began working part-time at the store and became familiar with the mechanics of watches and clocks. However, at 19 he joined the German navy, leaving six years later as a Captain.

After the navy, Prescher decided to study watchmaking and he won the single apprenticeship position offered yearly by IWC. The watch he crafted at the end of his four-year apprenticeship – which he completed in three years – was a rare, half-flying tourbillon and he came top of his class. Prescher then moved to Audemars Piguet in Frankfurt, where he also obtained his Master Watchmaker certificate. Then it was back to Switzerland to work in the restoration department of Gübelin where he had the opportunity to restore some of the world’s most iconic and complicated timepieces and to create bespoke watches for special clients.

Four years at Gübelin was followed by a brief spell at Progress Watch, then a position as Production Manager for Blancpain. In 2002 Prescher opened his own restoration atelier, making time to craft a watch of his own that became the world’s first double-axis tourbillon with constant-force device. This earned him his place as a candidate of the AHCI in 2003.

In 2004, Prescher stunned the horological world with the presentation of his incredible wristwatch Tourbillon trilogy comprising single-axis, double-axis and triple-axis tourbillons – all flying tourbillons with constant-force mechanisms. Alongside his tourbillon models, Prescher is also well known for his distinctive Tempusvivendi line in which the time is displayed by figures at the push of a button. His new Sculptura Una collection functions in the same way, but with conventional hands. In 2009, Prescher surprised again with a completely new development: an instant perpetual calendar with coaxial indications for optimal legibility.

In 2010 he presented themed “reduced to the max” the Mysterious Automatic Double Axis Tourbillon. A piece of art with an automatic movement implemented with upstanding mainplates left and right in the case. Indicating only hours, minutes, moonphase and calendar. The calendar is integrated in the horizontal rotating oscillating weight. As heart a flying tourbillon with constant-force in carriage, the tourbillon flying on two axes.

With “Choose your movement” he gave 2011 each aficionado the possibility to have an own piece of art with the own chosen design made by him and additional a closer look on the manufacturing of this piece. But not enough he realized a nautical project, where the Double Axis Tourbillon Nautica was born. Last but not least his newest goal a watch which ages. The NEMO Sailor collection with a case made in Copper bronze and steel replaced in time a fabulous patina. Followed by the Nemo Captain Triple Axis Tourbillon in an incomparable material combination for the case he used red gold and palladium.

Thomas Prescher NEMO SUB I

The world renowned independent watchmaker Thomas Prescher unveils his most ambitious horology project NEMO SUB I, a steampunk submariner inspired mechanical watch with an automatic‐winding bi‐axial tourbillon and triple‐piece case that is produced mostly from precision machined synthetic sapphire crystal.

Thomas Prescher combines sapphire crystal with 18k red gold and palladium for one of the most unique and original watch cases ever produced. Inherently avant‐garde, the NEMO SUB I case is divided into three main pieces that includes a larger central tube, as well as two smaller peripheral tubes on each side.

The purpose of the side tubes is to indicate the hours and minutes, as they are connected by a discreet gear shaft to the cylindrical mechanical movement that is placed inside the larger main tube.

For the first time ever Thomas Prescher has designed a movement with a half‐cylinder‐shaped automatic rotor that winds in each direction. Visible through the sapphire crystal tube case, it powers the carefully assembled bi‐axial tourbillon movement.

The front of the case has a view showing the tourbillon which spins on two axis points, each in 60 second rotations. The design makes for a visually stunning display as only Thomas Prescher ‐ a master of multi‐axis tourbillon – is capable of presenting.

Toward to rear of the main case is a second gyroscopic‐style (or cardanic‐spherical oscillator) automatic rotor which is used for a purely whimsical purposes. Its function is power the functioning propellers shafts located in each of the side tubes. These exist to complete the submarine fantasy in the world of Captain Nemo.

At the top of the NEMO SUB I case are two porthole‐style crowns that are used to either set the time or wind the mechanical movement. Thomas Prescher has ensured that despite the unorthodox nature of the NEMO SUB I design, any watch lover will understand its operation inherently.

Thomas Prescher’s journey into the steampunk aesthetic began in 2012 with the release of the Nemo Sailor and later in 2013 with the tourbillon‐based Nemo Captain. 2014 continues Thomas Prescher’s fascination with the world retro‐futuristic world of steampunk with the NEMO SUB I, while will be part of a limited edition of only five pieces. The initial piece will be produced in 2014, while the remaining four pieces will be delivered starting in 2015.

Thomas Prescher “Nemo Sailor” : The First Watch from Nemo Triptychron” Series

Swiss luxury watch brand Thomas Prescher unveils “Nemo Sailor” , the first timepiece of “Nemo Triptychron” series, as a part of their prestigious and sensational Archaeological Project. The newly introduced “Nemo Triptychron” line is inspired by Jules Verne’s “20’000 Miles Under the Sea” and different steampunk and art nouveau influences.

To create this exceptional timepiece, Thomas Prescher dived into a cosmos of images and stories of the late 19 th century. Surrounded by a collection of material of these topics he created a fantastic story around all the things he found and published it every few days like a diary about a new sensational archeological discovery.

A lot of attention was paid to this new way of letting the public participate in the creative process. It was clearly indicated that the story was invented but many readers were so fascinated that they have taken it for real. So the entire project became a fabulous success.The “Nemo Triptychron” story will be continued soon with the models Officer and Captain.

Important design elements are the porthole look of the bezel and back. Nameplates and index rings are inspired by old steam engines and steam punk design. The design highlights the materials used. For the lugs and front and back bezels saltwater resistant copper bronze was chosen, it has the right look and it ages with time to a wonderful patina. When softly re‐polished it gains the charming look of ancient things. Together with the stainless steel a fabulous contrast is created.
For the appliqués, on the dial but also on the case, a soft copper found its way into the design. The copper’s warm red color together with the traditional method of engraving the letters and filling them with paint round out the design to perfection.

The balance between free spaces on the dial and many little details gives the eye time and place to recover before starting again to discover the high end craftsmanship in the finish and the contrast between brushed surface and polished chamfer or the nameplate of the series in copper embracing the case at 9 o’clock.

For the oscillating weight an Art Nouveau window by Arnold Lyongrün gave the inspiration. It is a lovely composed detail as a fully closed slice. The transparent case back shows perfectly this special Nemo rotor with its copper appliqué and the white rhodium nameplates.

A really breathtaking detail is the crown. Inspired by the form of historic valves it is a bit the cherry on the cake of this marvel. The case measures 44 mm in diameter and 12 mm in height. Clients have the possibility to choose their own movement. Depending on the movement the height may differ a bit.As usual Thomas Prescher uses hand cut and hand sewn straps with crocodile leather on both sides.

Thomas Prescher makes hand‐made watches to the very highest standards and their finish is among the best available. So is his service. He offers modifications to client’s wishes for all his models.. His clients are accustomed to the fact that even their most exigent dreams are fulfilled.

Thomas Prescher Tempusvivendi Collection

Tempusvivendi originates in the golden era of artistic and technical horology of the eighteenth century. This period was not only renowned for some of the greatest horological inventions in history, but was also an epoch in which a watch combined valuable timekeeping properties with a high level of visual artistry and personal pleasure.

The roots of the Tempusvivendi line from Thomas Prescher originate in the early part of the eighteenth century, the golden era of artistic and technical extravaganzas – a time when horologists were developing the first watches with retrograde indications as an alternative to the everyday circular dial.

Thomas Prescher Tempusvivendi Collection

Retrograde displays are currently enjoying a great revival thanks to their clarity and extreme legibility. The hands move along a semi-circular arc; upon reaching 60 minutes or 12 hours, they spring back to the beginning and start all over again. Retrograde indicators are naturally used to present all kinds of information: date, months, days, temperature, barometric pressure, and much more.

Thomas Prescher Tempusvivendi Collection
Dragon

In the second quarter of the eighteenth century, the montre en bras represented the second stage of this retrograde development. These types of watches saw retrograde indications combined with etched or cast figures, moving the extreme legibility of the retrograde indication into the world of visual and artistic representation. These early pieces often depicted people, animals and even fully developed scenes.

Thomas Prescher Tempusvivendi Collection
Falcon

One extremity of the figure showed the minutes, while the other displayed the hours. For this reason, the montre en bras (literally «watch in arms») was also known as the bras en l’air, or «arms in the air,» and various technical types were developed. Some versions have the figure permanently in motion, always depicting the time.

Later, more advanced versions had the figures at rest, in a non-temporal state without indicating the time. When a button was pressed and held down, these figures showed the time on two retrograde scales. When the button was released, the figures returned to their resting state. These watches were a perfect example of how an artist combined legibility with beauty and personality in a fashion rarely seen today.

Thomas Prescher has further developed this exquisite and currently rare concept by allowing the wearer the choice of having the figure continuously show the time or allowing it to simply remain in its non-temporal state until called upon. This is achieved through the use of a complicated and ingenious gearing system that he developed. After closely studying and researching many original bras en l’air pieces while restoring them, Thomas Prescher was able to construct his own version, creating a special mechanism.

Thomas Prescher has always been specialized in the production of small series and custom-made watches to suit a client’s particular wish.

The Tempusvivendi line allows a variety of figures such as animals, human figures, symbols, emblems, and a great number of other subjects to be used. These can be created using any combination of engraving, enameling, and gem setting. Individual and unique timepieces are thus created, timepieces as one-of-a-kind as their owners. Each one, a work of art unto itself, tells its own story.

Thomas Prescher Triple Axis Tourbillon Regulator

Swiss luxury watch maker Thomas Prescher presents Triple Axis Tourbillon Regulator: The world’s only triple-axis flying tourbillon wristwatch.

A triple-axis tourbillon is extremely rare; a triple-axis tourbillon wristwatch even more so. However, Thomas Prescher’s triple-axis flying tourbillon is not simply extremely rare – it is absolutely unique.

Prescher’s Triple Axis Tourbillon Regulator features one of the world’s most exclusive and most difficult complications to assemble, set to stunning advantage in a jet-black natural onyx dial that contrasts beautifully with the pink-gold case. Regulator-style hours and seconds are each indicated in their own separate sub-dial, while the constantly animated tourbillon tracks the minutes during its one-hour rotation.

Thomas Prescher has both an affinity and a talent for complicated tourbillons: while his classmates were submitting simple movements for their watch at the end of apprenticeship school, Prescher presented a half-flying tourbillon that confirmed his position as the top of the form. In 2003 he presented the world’s first pocket watch with a flying double-axis tourbillon. On seeing Prescher’s pocket watch, one of his colleagues mentioned that he thought a double-axis tourbillon was impossible in the constrained space of a wristwatch. Prescher not only met but surpassed the challenge a year later with a wristwatch trilogy of single-axis, double-axis and triple-axis tourbillons.

At this extreme level of micro-mechanical sophistication and miniaturisation, watchmaking ceases to be about timekeeping and becomes pure art. Or perhaps that should read “arts”, because we have both the sublime static beauty of a fine painting in the harmonious forms and colours, as well as the graceful movements of the ballerina in the whorled path traced by the mesmerizing triple-axis tourbillon dancing apparently weightlessly in space.

Thomas Prescher Mysterious Automatic Double Axis Tourbillon

Guided by the idea to improve the perfect visibility of the central elements of his multi Axis Tourbillon Thomas Prescher composed a new breathtaking piece of art: Mysterious Automatic Double Axis Tourbillon.

Only time, Tourbillon, calendar and oscillating weight are visible. The movement is completely hidden. Place to hide the movement was found left and right in the case, hidden by the bezel. Because the space is very limited the parts of the movement had to be located on both sides.

Later, resting in a hammock the idea was born to create an automatic movement with horizontal swinging oscillating weight. To crown this exceptional piece of art, it was a logical decision to choose something special for the heart of this watch. The escapement with its beating balance has to be a flying Double Axis Tourbillon with constant force.

The idea to add a calendar to this creation came while observing some people entering a giant swing. They could move on the surface of the swing. Why not create an oscillating weight with integrated calendar indications and let the gravity take the calendar on the oscillating weight remains always horizontal.

This mysterious watch with its transparency led automatically to the wish to wear it from sides, front and back. With the calendar located on the flat side of the oscillating weight this indication is always facing upward. It can be read regardless of which side of the watch is up.

Respecting the aspects of harmony was an important point. Two crowns were used to keep the beauty of symmetry with. One crown is used for winding and the other for setting time and calendar. Both crowns build the main symmetry axis. Now it was necessary to build the optical balance between the oscillating weight on one side and the indication of time on the other side. For that reason a three dimensional moon was placed between the two barrels, indicating the hours and minutes.

Finally, placed on a turning axis, held by a carrying arm the carriage is rotating around itself. These two synchronized motions create a gyro scoping image immediately taking full attention.

Thomas Prescher Qatarwatch

That is normally the beginning of a time sculpture manufactured by Thomas Prescher. With excellent design, finest materials and perfect processing these dreams become reality step by step. Recently Thomas Prescher was asked if he could do a watch with a flag or national symbol. After asking for what country, the answer was: “Qatar”.

After a lot of research about this exceptional country, a picture of its Coat of arms inspired Thomas Prescher. The coat of arms of Qatar (Arabic: شعار قطر‎) shows two crossed swords in a yellow circle. Between the swords there is a traditional sailing ship called dhow, sailing over the waves beside an island with two palm trees. The yellow circle is surrounded by a white and brown band, which is divided horizontally with a zigzag line.
The realisation of the watch: One sword tip shows the minutes, while the other indicates the hours. With this retrograde system, after the swords reach the end of the index sector they jump back to the beginning to rise again. After pushing the button in the crown the swords move to a resting position to show the original coat of arms in gold and noble colours.

After a second push the swords move back to continue to show the actual time. Thomas Prescher has developed this exquisite concept to give the connoisseur the choice: Having the figure continuously showing the time or allowing it to simply remain in its non-temporal state. This could be only achieved through the use of a complicated and ingenious new system, which Thomas Prescher created specially for his watches, after studying and repairing old originals. Excellent design, the finest materials, perfect processing, invaluable beauty for generations.

Thomas Prescher Sculptura Una

The Sculptura Una watches boasts a unique double retrograde indication of time with continuously running display of minutes and jumping display of hours (temporal display). This Thomas Prescher watch is equipped with a special device for switching between the hands displaying the time and being in a non-temporal resting position (activated by button in crown.

Thomas Prescher Tourbillon Trilogy – Single Axis Tourbillon, Double Axis Tourbillon and Triple Axis Tourbillon

In 2003, Thomas Prescher became the first watchmaker to offer a double axis tourbillon pocketwatch. Just one short year later, he exhibited yet another world premiere: a triple axis tourbillon wristwatch as part of the Tourbillon Trilogy.

The Tourbillon Trilogy is a unique set of three tourbillon wristwatches comprising single, double, and triple axis flying tourbillons with constant force escapements. Each, encased in platinum, possesses a distinctive shape and various visual design features that share a common platform.

Thomas Prescher Tourbillon Trilogy - Single Axis Tourbillon, Double Axis Tourbillon and Triple Axis Tourbillon

Although single axis wristwatch tourbillons are no longer rarities today, only occasionally are they flying tourbillons, and it is absolutely unique to find a flying tourbillon with a constant force mechanism within a tourbillon cage. The Tourbillon Trilogy is only offered in platinum in a limited series of ten sets. However, separate editions of each wristwatch are now available individually and in various case materials.

Thomas Prescher Single Axis Tourbillon

The single axis tourbillon was invented by Abraham-Louis Breguet in 1801 to counteract the effects of gravity in pocket watches and improve their rates. Pocket watches were generally carried in the vest pocket in a vertical position, which was why Breguet’s invention only worked on pocket watches in this position.

Thomas Prescher Single Axis Tourbillon

Once the watch was laid flat, on a table for instance with the dial up or down, the entire effect of the tourbillon was voided and no longer affected the rate.

Thomas Prescher Double Axis Tourbillon

In the 1970s, an Englishman named Anthony G. Randall created a double axis tourbillon for clocks – more as an intellectual exercise than to actually address the issues of rate deviation mentioned above. He built a carriage clock based on these principles, adding the double axis tourbillon.

In a double axis tourbillon, the second axis revolves parallel to the dial, influencing the rate positively when the watch or clock is positioned with the dial up or down. Thus, this mechanism has an advantageous influence on the rate of all six positions.

Thomas Prescher Double Axis Tourbillon

Since the double axis tourbillon can only realize its full potential in wearable watches, Thomas Prescher first examined his possibilities in a pocket watch so that the feasibility of his vision could be examined and later added to a wristwatch version. It turned out that directly miniaturizing the same arrangement of components was not possible.

Thomas Prescher Double Axis Tourbillon

Problems concerning weight distribution, gearing, and friction of the micro mechanisms led to completely different reactions than in Randall’s clock since the smallest component of the new mechanism weighed a mere 0.0009 grams. The tourbillon had to be designed entirely new, most especially because Thomas Prescher wanted to create a flying tourbillon version.

Thomas Prescher Triple Axis Tourbillon

The creation of a set of three types of tourbillons required Thomas Prescher to invent a third individual construction. Inspired by Randall’s work, Richard Good became the first clockmaker to add a triple axis tourbillon to a carriage clock in the 1980s. Thomas Prescher took out his old apprenticeship notebooks containing his sketches and interpretation of Good’s work in creating a triple axis tourbillon carriage clock.

He wanted to modify this for use in a wristwatch. Spurred on by the success of his pocket watches, Thomas Prescher set to work further miniaturizing these multiple axis mechanics. He met the challenge and added a third axis that revolved once every hour.

The construction of such a tourbillon wristwatch was considered long impossible: it was thought that the movement height would be too great for practical use and that the weight of the additional components would not let enough energy get through to the balance. However, Thomas Prescher found a number of solutions to address these issues. The meaning of such a complicated timepiece is much more art for art’s sake than the search for any improvement of a rate.

Thomas Prescher Triple Axis Tourbillon

A triple axis tourbillon with its spiral-shaped movement takes up far more room in the space of a case than either the single or the double axis tourbillons. It is especially the unencumbered view that makes the tourbillon seem to hover in the air on its three flying axes. A triple axis tourbillon is not only a technical masterpiece of the art of watchmaking, but it is above all a piece of art that draws our eyes to it – magically – a kinetic sculpture of time.

More details

The creation of a tourbillon is considered the highest horological achievement for a watchmaker. Extremely high tolerances in combination with an extremely low weight  factor required for the manufacturing and assembly of the miniscule parts demand an especially balanced hand and precise eye.

Working on a tourbillon is one of the greatest challenges in watchmaking – a challenge that is magnified by double and triple axis tourbillons. Watchmaking at this level requires matching visual distinction to complement the extraordinary mechanisms.

At an early developmental stage of the Tourbillon Trilogy, Thomas Prescher decided not to use the same case shape for each piece, but to differentiate each tourbillon with its own personal visualization. The basic design elements that each of the watches share ensure recognition of the fact that they belong to together in the Trilogy set.

Thomas Prescher devoted the first sketches to the search for various basic geometric forms that would still retain formal harmony among the three tourbillons. From these sketches, the perfection of the circle for the extraordinary triple axis and the simple square shape for the single axis were defined as the two basic shapes of the set – like magnetic or electrical impulses; the plus and minus. The carrée cambrée shape of the double axis tourbillon’s case represents the metamorphosis of the square to the circle, a transient in motion between two extremes.

The so-called divine proportions form the mathematical rule of perfect harmony, which originates in the most beautiful geometrical examples found in nature. Thomas Prescher followed this rule to come up with the proportions of the main dials and little subdials. The smallest unit is the second, so the subsidiary dial for seconds is logically the smallest, with the hour and minute subdials proportionally larger according to the rule of divine proportions.

The perfect size of the tourbillon window, which allows a view of the open heart of the movement itself, was determined in exactly the same manner.

Guilloché generally evokes an old-fashioned, classic eighteenth century atmosphere on a watch dial – logical, since this form of embellishment was used on watch dials made by the hands of the great masters from that period and beyond. For the dials of the timepieces in the Tourbillon Trilogy set, Thomas Prescher invented a new guilloché pattern that allows the eye an undistracted view of the tourbillon’s highly complex motion.

The traditional creamy silver, even patterned guilloché décor would have been too «antique» in feeling. The solution was found in the creation of a unique handmade guilloché pattern especially designed for the set that Thomas Prescher christened Guilloché Triangulair. Here, another basic form, that of the equilateral triangle, was chosen for the guilloché pattern’s cell structure, providing a higher number of sides to the viewer that seem to «change direction » under different lighting situations – always in motion, just like the tourbillon itself.

The majority of tourbillon wristwatches on the market today are not of the flying variety; that is to say, they are generally outfitted with a fairly large tourbillon bridge on the dial side. Even if these bridges are beautiful in shape, they continue to block the view of the tourbillon.

The flying tourbillons created by the Thomas Prescher have no need for such a bridge, thus providing a supremely clear view of the tourbillon escapement. This is accentuated by the fact that the tourbillon opening is transparent on both the dial and movement side, providing a view of the tourbillon so clear that it seems suspended in space.

Many different forms of decoration are traditionally available for gracing the movement, or back, of the watch. Once the decision was made to create a new guilloché pattern for the dial, Thomas Prescher abandoned more traditional decorative patterns such as Geneva stripes as they did not fit his whole artistic vision for the Tourbillon Trilogy.

In detailed studies of the dial and movement decoration, he developed a solution in which both are joined to form a unit. Inspired by music, the existing triangular pattern of the dial was repeated three times in slightly different variations, like in a sonata.

Thus, the pattern characterized by art deco developed into an ever more complex form as it progressed from the single axis version to the triple axis model. It climaxes in the floral design elements of the bridge on the triple axis tourbillon, which acts, similar to a sonata, as a counterpoint. In this way, each individual dial fully harmonizes with its movement decoration, and the three models of the Tourbillon Trilogy melodiously harmonize with each other.
