Barcelona based Atelier de Chronométrie presents the AdC30 Only Watch, a one-off timepiece specially created for the Only Watch 2023 charity auction to support research into Duchenne muscular dystrophy.
Specially designed and handcrafted for the prestigious auction, the AdC30 Only Watch is a time only model with sub-seconds at 6 o’clock. It has an 18k grey gold round case with stepped lugs, concave bezel and case-back.
The design is completed with a superb sandwich dial with 18k rose gold and blued steel leaf hands. This timepiece also comes with the new in-house calibre M284.
Atelier de Chronométrie is participating in the prestigious biannual charity auction for the second time. For the previous edition, the company created the AdC21 Only Watch 2021 unique piece, which was auctioned for an amount of CHF 95,000.
The new in-house Calibre M284 boasts a special handmade frosting decoration different from the regular M284 version. Totally aligned with the brand DNA, it evokes the past with an architecture inspired by the calibres from the 1940’s. It comes with a number of high-end traditional finishes such as handmade frosting, anglage, perlage, polished countersinks, straight graining, étirage des flancs, black polish and beveled screws.
