Reference 331.10.42.51.01.002 revisits one of Omega's most celebrated designs — the Speedmaster '57 — and pairs its heritage silhouette with contemporary watchmaking credentials. The round 41.5mm stainless steel case, measuring 16.5mm in thickness, is finished in a combination of brushed and polished surfaces and fitted with a transparent case back that reveals the movement within.
Beneath the anti-reflective, scratch-resistant sapphire crystal sits a black dial configured for chronograph use, while the fixed bezel frames the display cleanly. Water resistance is rated to 100 metres / 330 feet. The watch is secured to the wrist via a stainless steel bracelet with a push-button folding clasp.
Powering the watch is an automatic chronometer movement that carries COSC certification, confirming its precision meets the Swiss Official Chronometer Testing Institute's exacting standards. The Co-Axial escapement is central to Omega's movement architecture in this reference, representing a meaningful step in the Speedmaster '57 lineage.
