310.20.42.50.02.001Ref

Debuting in 2024 as part of the Moonwatch Professional collection, the ref. 310.20.42.50.02.001 blends historically faithful Moonwatch architecture with a two-tone stainless steel and Moonshine Gold construction: a 42 mm asymmetrical steel case, Moonshine Gold bezel with black ceramic tachymeter (dot over 90), 47.50 mm lug-to-lug, 13.18 mm thick, 5 bar water resistance, and sapphire crystals on both front and caseback. The silver stepped dial, inspired by fourth-generation Speedmasters, carries applied Moonshine Gold markers and logo, Moonwatch-style hands, and a tri-compax chronograph (small seconds, 30-minute, 12-hour). Power comes from the manual-winding, METAS-certified Co-Axial Master Chronometer Calibre 3861 (3 Hz, ~50-hour reserve, 15,000 gauss, silicon balance spring, rhodium-plated), paired with a stainless steel bracelet with Moonshine Gold centre links and a foldover clasp with comfort adjustment.
