The Speedmaster Moonwatch is one of the world’s most iconic timepieces. Having been a part of all six moon landings, the legendary chronograph is an impressive representation of the brand’s adventurous pioneering spirit. Presented on a polished-brushed 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, a white lacquered step dial with applied OMEGA logo and indexes, Moonwatch style hands, and the famous dot over 90 on the black anodised aluminum bezel ring. The watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 3861, which powers the small seconds sub-dial, 30-minute recorder and 12-hour recorder, along with the central chronograph function.<ul><li>Between lugs Open Case Measurement Modal: 20 mm</li><li>Lug-to-lug Open Case Measurement Modal: 47.5mm</li><li>Thickness Open Case Measurement Modal: 13.2 mm</li><li>Case diameter Open Case Measurement Modal: 42 mm</li><li>Case: Stainless Steel</li><li>Dial color: White</li><li>Crystal: Domed scratch-resistant sapphire crystal with anti-reflective treatment inside</li><li>Water resistance: 5 bar (50 metres / 167 feet)</li><li>Total product weight (approx.): 140 g</li><li>Caliber: Omega 3861</li><li>Movement Type: Manual winding</li><li>Power reserve: 50 hours</li><li>Anti-magnetic</li><li>Chronograph</li><li>Chronometer</li><li>Master Chronometer Certified</li><li>Small seconds</li><li>Tachymeter</li><li>Transparent caseback</li><li>Strap Type: Stainless steel bracelet</li><li>Buckle Type: Stainless steel foldover clasp with comfort setting</li></ul>OMEGA Style#: O31030425004001
