Omega Speedmaster Professional Moonwatch, 311.30.42.30.01.005

The Omega Speedmaster Professional Moonwatch, reference 311.30.42.30.01.005, is a manual-winding chronograph wristwatch with a 42 mm stainless steel case and a black dial. It belongs to the Moonwatch Professional collection. This example is used, rated Good, and offered as authentic. It is listed as a men's watch and comes with original papers; the original box is not included. For a buyer comparing steel chronographs, the reference number and the supplied scope of delivery define what is being offered.

Because the movement is manual, the watch is wound by hand rather than through wrist motion, so winding becomes part of the routine of wearing it. The stainless steel case and matching stainless steel bracelet give the watch a consistent metal appearance from head to band, while the black dial provides contrast for reading the chronograph layout. A sapphire crystal covers the dial. The 42 mm case diameter is the figure to compare against a wrist or another watch already owned; the round shape keeps the profile conventional. The bracelet is stainless steel, so the watch is worn on a metal bracelet.
