Reference 331.10.42.51.01.001 pays homage to the original 1957 Speedmaster design while housing a contemporary automatic chronometer movement. The round stainless steel case measures 41.5mm across and 16.5mm thick, with a transparent case back that reveals the certified calibre within. Water resistance is rated to 100 metres, and the push-button folding clasp secures the stainless steel bracelet with a brushed and polished finish.
A black dial sits beneath anti-reflective scratch-resistant sapphire crystal, lending the watch strong legibility and a commanding on-wrist presence. The fixed bezel completes the purposeful, sport-oriented silhouette that has defined the Speedmaster line for decades. The movement carries COSC chronometer certification, attesting to its precision across a range of conditions.
The chronograph complication adds a practical timing function true to the watch’s racing-inspired roots. This example is presented in new and unworn condition, making it a compelling choice for collectors and enthusiasts drawn to Omega’s most storied sport series.
