Maîtres du Temps, the world renowned horology atelier based in La Chaux-de-Fonds, unveils their latest timepiece Chapter One Tonneau Transparence Titanium: C1-3T.
Barely visible to the naked eye, the sapphire crystal replaces the dial revealing the handiwork of the master watchmaker: impeccably finished bridges, precisely beveled edges, and a symphony of mechanical complexity. The Transparence Titanium, presented here in a limited edition of 11 pieces, unveils the heart and soul of a rare timepiece with an outstanding personality. The long and flowing curves that shape the case give it an air of nobility and power that embodies the outstanding complexity of the original movement. The ease of reading and setting the numerous display indications of Chapter One would almost make the user forget that we are facing a world’s premiere in terms of combinations of complications with 558 components.
Chapter One, a real masterpiece of horology, was the first timepiece in the world to feature a tourbillon movement incorporating a mono-pusher column wheel chronograph, retrograde date, retrograde GMT, and phase of the moon and day of the week indications displayed on their own distinctive high-precision cylinders.
Efficiently transmitting power 90° to the two high-precision cylinders and ensuring that they work simultaneously with the time, date, GMT, and chronograph was an immense technical challenge. The harmoniously integrated cylinders, for example, had to be both large enough to be easily read and small enough to be ultra light and homogeneous with the case. Scintillating, laser-pierced moon and stars on the outer cylinder of the moon phase indication add to the stellar elegance of Chapter One. The high-precision cylinders are made of anodized aluminium offering solidity while being lightweight. The painting adorning the cylinders is applied by hand based on a traditional process.
The three-dimensional, arched and bold design of the Chapter One evokes more a sports car than a wristwatch. The different finishes obtained through successive brushings on the titanium material strengthen this appeal. Polished, satin or sanded finish, all the case surfaces benefit from a specific surface treatment. This feat is even more outstanding as the hardness of the material makes any surface treatment a challenge. As a comparison, the decoration of this titanium case requires twice the time of a similar gold version.
The curves of the four correctors integrating a locking system follow a curved line ending in an imaginary spot in order to perfectly marry the elegant design of the case. Manufactured in 18K gold, they incorporate 14 different components and were developed exclusively for Chapter One.
The case back screws are also manufactured of 18K gold.
The sapphire dial designed for Transparence is a work of art and an example of the highest level precision engineering. The 0.40 mm, ultrathin high-tech sapphire dial is cut and precisely laser-pierced more than twenty times to provide holes for the anchors to securely fasten the appliqués that mark the passage of time. The fastidious process of machining the multi-beveled minute track, which includes hand-painted Super-LumiNova indices, illustrates that the level of detail in Chapter One Tonneau Transparence Titanium is not just limited to the movement. While the meticulous process of fitting the tourbillon cage to the fine, nearly invisible dial is reserved for only the most accomplished of watchmakers who dare to take on such a complicated assembly, the result is an extremely legible timepiece with a breathtaking view into mechanical mastery.
A look at the dial shows in the center; the hour, minute and chronograph 60 second hand, the retrograde date at 3h, the tourbillon and the day of the week cylinder at 6h, the retrograde second time zone (GMT) at 9h, the 60 minutes chronograph counter and the moon phase cylinder at 12h.
The opening at 6h allows a unique view onto the superb finish of the tourbillon cage with its finely decorated M shaped cage bridge standing for Maîtres du Temps. The tourbillon cage makes one rotation in sixty seconds showing the motion of the elapsing time.
Equally notable is the addition of the precious metal finish chronograph bridge visible through the octagonal sapphire display back. Through a patented plating process, four precious metals belonging to the platinum family—platinum, rhodium, ruthenium, and palladium—combine to give the chronograph bridge the darkened appearance unique to the Chapter One Transparence collection.
