What to know
Created for Isetan’s 50th anniversary in Japan, the AdC37 is a unique 37mm dress watch built around a handmade 18k grey-gold Calatrava case. Stepped lugs and a concave bezel frame a blue Grand Feu enamel dial, finished with applied white-gold baton markers and handmade white-gold dauphine hands.
The display is powered by Atelier de Chronométrie’s hand-wound M284 calibre. The 30mm movement has 19 jewels, runs at 18,000 vibrations per hour and provides a stated 48-hour power reserve. Its rhodium-plated Arcap bridges are finished with hand-executed Côtes de Genève, anglage, perlage and polished countersinks. A rose-gold number plaque engraved “37” distinguishes the movement, visible through the rear sapphire crystal.
