OMEGA Speedmaster '57 40.5mm Green Dial Chronograph Leather Strap Watch 332.12.41.51.10.001. 

Inspired by the 1957 Speedmaster watch, this stylish Omega Speedmaster ’57 Chronograph watch combines an entrancing deep green dial with a matching green leather band and a brushed stainless steel bezel with a tachymeter scale for measuring speed based on distance. The 40.5mm model is crafted from stainless steel and offers a water resistance of 50 meters. Its green dial offers a sub-counter at 3 o’clock for the 12-hour function and a 60-minute counter at 9 o’clock. These sub-dials are balanced by a date window in black at 6 o’clock, protected underneath a sapphire crystal glass front with anti-reflective and scratch-resistant properties. This men’s Omega Speedmaster ’57 watch is powered by the manual-winding Omega Co-Axial Chronometer Calibre 9906, which provides a 60-hour power reserve. It sits behind a sapphire crystal glass exhibition caseback, putting on show its rhodium-plated finishes with Geneva waves in arabesque. To complete its iconic look, the green Omega Speedmaster ’57 watch is fitted on a comfortable matching green leather strap with a stainless steel buckle featuring the Omega lettering in positive relief across its surface.
