Omega Speedmaster Moonwatch Professional 310.32.42.50.04.001 42 mm Steel White Dial Black Rubber Strap Watch for Men

A white lacquered step dial meets an integrated black rubber strap on this Speedmaster Moonwatch Professional. The underside of the strap is moulded with the lunar surface in positive relief, and the 42 mm asymmetrical stainless steel case carries a black anodised aluminium bezel ring with the dot over 90, following the fourth-generation design worn on the Moon.

Applied OMEGA logo and indexes and Moonwatch-style hands are set against the white dial, with sapphire crystal on the front and the caseback. The manual-winding Calibre 3861, driving small seconds, 30-minute and 12-hour recorders and the chronograph, is a METAS-certified Co-Axial Master Chronometer resistant to 15,000 gauss, with a 50-hour power reserve. A steel foldover clasp secures the strap.
