Atelier de Chronométrie AdC8: a hand-finished split-seconds chronograph

The AdC8 is a distinctive piece of modern independent watchmaking, informed by mid-century chronographs rather than current industrial construction. Its 18-carat grey-gold case is sculpted around polished teardrop lugs and carefully integrated chronograph controls. The black galvanic gilt-style dial features a pulsations scale, applied Breguet numerals and hand-finished indications to balance visual density with legibility.

At its heart is calibre 8, built on a vintage Venus 185 split-seconds chronograph ébauche. Around fifty new components were made by hand, with the rest extensively reworked and decorated. The manual movement delivers approximately 36 hours of power reserve and beats at 18,000 vibrations per hour. The AdC8 was a finalist in the chronograph category at the 2020 GPHG, placing its artisanal detail in the spotlight.
