Louis Moinet Chronosphere

Ateliers Louis Moinet presents CHRONOSPHERE – the first chronograph to feature a constantly moving retrograde seconds system. Both fun and interactive, this new chronograph complication is it based on a completely new development – the only one in the world to bring together a retrograde system, totalizer, chronograph, and movement animation.

To achieve this, a column wheel mechanism was designed, in which a new approach was taken to incorporate the retrograde complication. This involved coming up with an ingenious “starwheelslide bar” system. Made completely from titanium so as not to affect the workings of the watch, the system lies at the heart of the animation.

It features a rack at 9 o’clock and a starwheel at 6 o’clock. The system is extremely precise, launching a hand along a 10-second journey (between 5 o’clock and 7 o’clock) before it snaps back to its original position to begin another cycle. It also brings to life the tens of seconds counter (from 0 to 5), whose jumping disc displays the relevant indication in the window located in the middle of this section.

The other major complication is the chronograph, as evidenced by a large central hand (60 seconds) made from composite material and decorated with a red dot. Meanwhile, the counter at 2 o’clock counts up 30-minute periods.

The heart of the movement can also be seen on the front of the watch, where the spring balance is on display, vibrating at a frequency of 4 Hertz (at 11 o’clock) – the final detail in the overall animation.

The bottom of the flange is made from titanium, adding to the lightness of the timepiece, and is covered with a high-temperature vacuum-moulded translucent material.

This enables it to be through-coloured –and the transparent coating discreetly highlights the chronograph indications. The hours and minutes hands are in Moinet blue, making it easy to read the time.

The titanium case is an original design, displaying Louis Moinet’s signature on the caseband. The lugs are decorated with black zircon and a screwed setting.

The two-part bezel of the Louis Moinet Chronosphere is a hallmark feature of the brand, with its 6 screws fitted at a 17-degree angle. The two box-type sapphire crystals have been treated with a non-reflective coating on both faces.

The pushers are decorated with a “Clous de Paris” pattern, while the crown protector is itself specially protected. The Louisiana alligator strap and alligator lining are hand-sewn; the strap is fitted with a clasp bearing Louis Moinet’s fleur de lys emblem.
