SPEEDMASTER '57-40.5 MM, STEEL ON LEATHER STRAP
Ref 332.12.41.51.01.001
DESCRIPTION
The Speedmaster is one of OMEGA’s most iconic timepieces. Having been a part of all six lunar missions, the timepiece is an impressive representation of the brand’s adventurous pioneering spirit.
This 40.50 mm model, inspired by the legendary 1957 original, features a stainless steel case and a black dial with recessed hour markers showing vintage Super-LumiNova from beneath. Along with rhodium-plated “Broad Arrow” hands, there is a date window at 6 o'clock, a small seconds subdial at 9 o’clock, and 12-hour and 60-minute chronograph recorders on the subdial at 3 o’clock.
The brushed bezel includes a blackened tachymeter scale, while on the caseback, there is a “Speedmaster ‘57” engraving as well as a flat sapphire crystal with an anti-reflective treatment inside.
The watch is presented on a brown leather strap with an OMEGA logo in postive relief on the buckle, and is driven by the manual-winding OMEGA Co-Axial Master Chronometer Calibre 9906.
