The Chronomètre FB RES Jubilee Edition has been released to celebrate the 70th anniversary of Sincere Haute Horlogerie, a long-time partner of Chronométrie Ferdinand Berthoud. This exclusive series is limited to just three pieces, featuring a platinum octagonal case and a satin-brushed salmon dial. Designed in collaboration with Sincere, each watch is engraved with Sincere’s logo at nine o’clock, symbolizing infinity. The timepiece includes an advanced movement system with a fusee-and-chain mechanism for constant force and a one-second remontoir d’égalité for precise timekeeping, delivering a deadbeat seconds display. The skeletonized dial and hand-polished angles showcase the artistry and craftsmanship, requiring over 250 hours to complete.
