Presented on a polished-brushed five-arched-links-per-row bracelet, this 42 mm Moonwatch in stainless steel features sapphire crystal glass on the front as well as on the caseback. Inspired by the 4th generation Speedmaster style worn on the moon, it also includes an asymmetrical case, black step dial with applied OMEGA logo and the famous dot over 90 on the anodised aluminium bezel ring.
