Atelier de Chronométrie has swiftly emerged as one of the most revered voices in contemporary independent watchmaking. The atelier is celebrated for its unwavering commitment to traditional technique —eschewing CNC machinery in favor of hand tools and time-honored methods. Each timepiece is a singular commission, born of intimate collaboration between maker and collector.

Housed in a 36mm diameter case in 18K grey gold—a noble, untreated alloy of white gold — the watch features beautifully sculpted stepped lugs, a concave bezel, and a domed sapphire crystal. Every exterior component is painstakingly hand-finished and crafted from the same lustrous grey gold. The dial, executed in a two-tone galvanic silver and rose palette, is a study in texture and restraint. A sablé-finished chapter ring, punctuated by applied Roman numerals and dot markers, encircles vertically satin-brushed sectors, while the small seconds register is classical engine-turned guilloché.

At the heart of the watch lies a mechanical tour de force: a hand-wound caliber developed entirely in-house and constructed from untreated, natural Arcap, a copper-nickel alloy. The AdC #20 ranks among the brand’s most technically and artistically accomplished creations. Its painstaking hand-finishing is exemplary: hand-executed 90-degree Côtes de Genève, sharply beveled edges, mirror-polished countersinks, and hand-drawn flanks. The black-polished swan neck regulator and screws gleam with exceptional clarity, capturing the light with quiet brilliance.

This is the only movement Atelier de Chronométrie will ever produce in this configuration. Offered in brand-new condition with its full set of accessories, the AdC #20 stands as a powerful tribute to the timeless art of handcraft in watchmaking.
