Reference 331.12.42.51.01.001 brings the Speedmaster '57 lineage into sharp focus with a round 41.5mm stainless steel case measuring 16.5mm thick. The black dial sits beneath an anti-reflective, scratch-resistant sapphire crystal, while a fixed bezel frames the layout with understated restraint. A transparent case back invites a view of the movement within, and water resistance extends to 100 metres / 330 feet.
Inside beats an automatic chronometer-grade movement featuring Omega's Co-Axial escapement, earning COSC certification for its precision timekeeping. The chronograph complication adds a layer of functional depth that stays true to the watch's racing-inspired origins.
A brown calfskin leather strap with a push-button folding clasp completes the package, lending warmth and comfort to the wrist. This example is presented in new/unworn condition.
