The J12 Rétrograde Mystérieuse encloses a movement far from usual one. Launched for the 10th anniversary of the J12 the name RMT10 is very eloquent about its conception:

In addition to the vertical and retractable crown operated by fi nger pressure at 3 o’clock on the dial, the manual wind movement developed by Renaud et Papi (LOCA SA) has 315 components.

For the first ten minutes, hours and minutes are read very traditionally in the middle of the watch . At the tenth minute of the hour, the minute hand reverses its rotation and sets off again anti-clockwise. Therefore, it is moving backwards and will take ten minutes to return to its traditional position at the twentieth minute. For this anti-clockwise revolution of 300° (50 min. x 6/min.), the minute hand goes backward at the rate of five minutes of dial every minute. During these ten minutes (“retrograde” period), every minute passed can be read on a discfigured 11 to 19 in a magnifying aperture. This digital disc only moves slowly during this interval of the minute hand moving backwards. It remains in a neutral position (no figures) during the fi fty minutes of the normal rotation of this hand. After the ten minutes of moving backwards, reading the time returns to normal.

At 11 o’clock, a hand power reserve shows the operating time for the movement until its next manual winding (the movement is designed to operate for about ten days, i.e. 237 hours, once the two parallel barrels are fully wound

The minute tourbillon run at a frequency of 3Hz and the bridge is made with sapphire and high-tech ceramic
Winding system exclusive. The black balance has four adjustable screws in 18 carat gold.

CROWN AND PUSH-PIECES

Crown and push-pieces

Protected by a patent registered by CHANEL, the crown has three major groundbreaking features:

1. The design of a vertical retractable system whereby the crown can enter and leave the case by simple pressure

2. The construction of a perpendicular connection between the movement and the crown stem

Function selection mechanism

3. The creation of a mechanism with two high-tech black ceramic push-pieces recessed into the bezel to activate the crown functionality

- Push-piece no. 1 at 4 o’clock: activates the movement winding function

- Push-piece no. 2 at 2 o’clock: activates the time setting function

The plate is made from ceramic and the sapphire crystal on top of this movement offers the possibility to appreciate its fine achievement.
