Movement featuring additional time zone with minute setting. 316 components. "Côtes de Genève", bevelled bridges.
The calibre PF337 of the Toric Hémisphères Rétrograde features two time zones, each accurate to the nearest minute. It was a world first. A module that controls the second time zone can be indexed to the main movement or disengaged to allow independent adjustment using the small crown at 2 o'clock. The main crown at 3 o'clock is used to wind the movement and set the time of the two paired time zones. This exceptional self-winding movement has a double series-mounted barrel for improved isochronism and rate regularity, with a power reserve of 50 hours.
