The Omega Seamaster Diver 300M reference 210.62.42.20.03.001 is a 42mm luxury diving watch featuring a case crafted from 18K Sedna Gold, Omega’s proprietary rose gold alloy. The timepiece is characterized by its polished blue ceramic bezel with a Ceragold diving scale and a matching blue ceramic dial decorated with laser-engraved waves. The skeleton hands and raised indexes are also finished in 18K Sedna Gold and filled with white Super-LumiNova for legibility. It is equipped with a blue rubber strap featuring an 18K rose gold pin buckle and a scratch-resistant sapphire crystal with anti-reflective treatment on both sides.
In terms of complications and technical features, the watch is powered by the OMEGA Master Chronometer Calibre 8801, a self-winding movement with a 55-hour power reserve that is visible through a transparent sapphire crystal caseback. The movement is METAS-certified for precision and resistance to magnetic fields reaching 15,000 gauss. Designed for professional use, it includes a date window at the 6 o’clock position, a helium escape valve at 10 o’clock, and a screw-in crown, supporting a water resistance of 300 meters.
General reviews of this Seamaster model emphasize its balance of high-end jewelry aesthetics and robust tool-watch functionality. Critics often praise the unique hue and durability of the Sedna Gold, as well as the technical superiority of the Master Chronometer movement. While the 42mm case size and non-tapering strap design are noted for their significant wrist presence, the watch is frequently highlighted as offering exceptional value and finishing within the luxury diver segment. Some users have noted that the gold construction adds substantial weight compared to stainless steel or titanium alternatives, though it remains a highly sought-after piece for collectors seeking a prestigious yet capable diver.
