Omega Speedmaster Moonwatch Professional 310.32.42.50.01.002 42 mm Steel Black Dial Black Leather Strap Watch for Men

A black calf leather strap and steel foldover clasp give this Speedmaster Moonwatch Professional a dressier presentation. Sapphire crystal covers both sides of the 42 mm asymmetrical stainless steel case, whose domed front sits over a black step dial carrying an applied OMEGA logo, framed by an anodised aluminium bezel ring with the dot over 90.

Through the caseback, the manual-winding Calibre 3861 is on view, driving small seconds, 30-minute and 12-hour recorders and the chronograph. It is a Co-Axial Master Chronometer certified by METAS, resistant to 15,000 gauss, with a free-sprung silicon balance spring and a 50-hour power reserve. The design follows the fourth-generation Speedmaster worn on the Moon; water resistance is 50 metres.
