This movement includes a secondary time zone with minute-level adjustment and consists of 316 parts, featuring bevelled bridges and "Côtes de Genève" decoration. The Toric Hémisphères Rétrograde calibre PF337 was a world-first, allowing the second time zone to be synchronized with the main movement or adjusted independently via the 2 o'clock crown. A double series-mounted barrel provides 50 hours of power reserve with enhanced isochronism and rate stability.
