Description

Self-winding movement with regatta chronograph, introduced at SIHH 2017. It is capable of a [max] 10 minute countdown before instantly starting a timing sequence. It consists of 650 pieces including 72 jewels.

The regatta feature, located at the center of the dial, displays the countdown with an arrow pointing at the yellow minute scale from 0 to 10. Easily readable, this hand can be set with a pusher located at the 10 o’clock position and moves in a counterclockwise direction when when the countdown starts. At the same time, the two-way seconds hand of the chronograph ticks away the seconds – in a counterclockwise direction – until the countdown comes to an end. When the countdown reaches zero signaling the start of the race, the seconds hand instantly starts moving in the clockwise direction and begins timing the race, measured by an hours and minutes subdial at the 6 o’clock position.
