Omega Speedmaster '57 332.10.41.51.10.001 40.5 mm Steel Green Dial Watch for Men

Green is the colour of this Speedmaster '57, a 40.5 mm chronograph in stainless steel inspired by the model of 1957. White Super-LumiNova fills its Broad Arrow hands and rhodium-plated hour markers, while the dial layout places small seconds at 9 o'clock, the 12-hour and 60-minute counters together at 3 o'clock, and the date at 6 o'clock.

Framing the dial, a brushed bezel shows a blackened tachymeter scale. Manual-winding Calibre 9906 combines a column wheel with a Co-Axial escapement and is certified Master Chronometer by METAS, resistant to 15,000 gauss, with a 60-hour power reserve. The caseback pairs a “Speedmaster ’57” engraving with a flat sapphire crystal, and the matching bracelet uses OMEGA's patented comfort release adjustment.
