Mühle-Glashütte Robert Mühle Mondphase Limited Edition

To mark the company’s 150th anniversary year in 2019, Mühle-Glashütte created a special edition collection incorporating its third new complication designed in house. Alongside its new moon phase display, the impressive 42-millimetre-large platinum, red gold or stainless steel case of this limited special edition also houses the company’s very own up/down display and the Mühle hand date.

Mühle-Glashütte has been devoted towards achieving precise measurement for 150 years. In celebration of this fact, the manufacturing workshop based in the German town of Glashütte is launching a special edition aligned with the moon in its anniversary year of 2019.

After maximum precision has defined the work and products of MühleGlashütte right from the very start, it comes as no surprise that the three new time measuring instruments from the “R. Mühle & Sohn” manufacturing line keep up the good work. In fact, the newly designed moon phase display of the “RMK 04” Robert Mühle calibre is so precise that an impressive 122 years must pass before it deviates from the actual position of the moon by even a day.

The design of the lunar disc of the new special edition model also reflects this focus on precision with a capital P. The moon displayed on the disk is the result of meticulous work by the watchmakers at Mühle-Glashütte, who have carefully reproduced the large and small craters of this astronomical body located more than 384,000 kilometres away. This impressive feature is surrounded by the night sky in a dark blue that makes it stand out even more. It is produced using an anodised aluminium plate onto which the intricate details of the moon are laser engraved.

As an important component of the new moon phase module, this plate is firmly attached to the movement itself. Above it, a moon shadow plate slowly revolves, using its two small cover discs to depict the current appearance of the moon. In the case of a new moon, one of the discs is positioned directly above the moon on the display and completely covers it. When there’s a full moon, the two cover discs move into a horizontal position and leave Earth’s closest neighbour clear for all to see.

This exclusive moon phase mechanism contains a total of 22 components and can be found in a third of the module plate of the hand-wound movement on the face side of the watch. The other two thirds of the plate are home to the up/down display designed in 2014 and Mühle’s very own pointer date from 2016. These complications are comprised of 25 and 35 components respectively. This means that the manufacturing line’s new calibre contains a staggering total of 202 components and is one of the most complex movements manufactured by Mühle-Glashütte.

Such intricate work deserves to be put on show, which is why wearers can admire this perfectly honed movement through the watch’s sapphire crystal case back. Watch connoisseurs are sure to love the model’s engraved balance cock with a patented woodpecker neck regulation, while the rare three-fifth plate of the Robert Mühle calibre features three screwed gold chatons, bevelled edges and a skeletonised escape wheel cock that will definitely put a smile on their face.

On top of all this, the plate also houses the complex Glashütte long-slot click and the watch’s crown and ratchet wheel. These last two components stand out against the wide lines of the plate’s ribbed finish thanks to their elegant double solarisation.

The new Robert Mühle Mondphase model, which is limited to a total of 150 timepieces, is not only stunning on the inside but also on the outside thanks to its newly designed case with an impressive diameter of 42 millimetres, perfect for the world of business.

Mühle-Glashütte Robert Mühle Mondphase Limited Edition gold watch

The case is available in not one, but three different materials: stainless steel, 18-carat red gold or 950 platinum. By producing the Robert Mühle Mondphase in stainless steel, Mühle-Glashütte is paying tribute to the very beginning of its manufacturing line, with the silver-coloured face with blued hands adopting the look of the Robert Mühle Auf/Ab and Kleine Sekunde models from 2014 and reproducing it in a new 42-millimetre case.

Alongside the total of 100 Robert Mühle Mondphase stainless steel timepieces being produced, Mühle is also going one step further by manufacturing 25 Robert Mühle Mondphase GOLD models with a white face and 25 Robert Mühle Mondphase PLATIN watches with a dark blue face.

All of these models feature faces with clearly marked minute graduation and applied hour indices in order to keep up the Mühle-Glashütte tradition of offering precision at its very best. In the 3, 6, 9 and 12 o’clock positions, the fine lines used as indices are replaced by a small diamond-shaped marker, a small yet effective detail that has a dynamic impact on the otherwise straightforward face, thus encouraging wearers to look at and admire their timelessly elegant time measuring instruments over and over again.

Another reason to adore these new limited-edition models is their outstanding accuracy values. Once its components have been carefully finished and assembled, every Mühle movement is put to the test in five different positions and, thanks to the patented woodpecker neck regulation, regulated to achieve accuracy values of between 0 and a maximum of +8 seconds per day. This precision target forms the heart of Mühle-Glashütte’s very own regulation standards and helps to ensure that its watch wearers are never too late because of their time measuring instruments. It also means that the hour, minute and second display of the Robert Mühle Mondphase doesn’t need to rely on the moon but can instead put its trust in its own reliable components.
