Omega Speedmaster '57 332.12.41.51.10.001 40.5 mm Steel Green Dial Green Leather Strap Watch for Women

Green leather matches green dial on this Speedmaster '57, worn on a non-grained calf strap whose stainless steel pin buckle carries an OMEGA logo in relief. The 40.5 mm steel case takes its cue from the 1957 original, and white Super-LumiNova coats both the Broad Arrow hands and the rhodium-plated hour markers for strong contrast.

Small seconds sit at 9 o'clock, a dual 12-hour and 60-minute recorder at 3 o'clock and the date at 6 o'clock, driven by the manual-winding Calibre 9906: column wheel, Co-Axial escapement, Master Chronometer certification by METAS, 15,000-gauss resistance and a 60-hour power reserve. A blackened tachymeter scale runs around the brushed bezel, and a flat sapphire crystal sits in the engraved caseback.
