OMEGA Seamaster 300 Edition 2021, New Stainless Steel Models

First created by OMEGA in 1957, the Seamaster 300 represents one of the most famous watches in underwater history. Admired by generations of divers, it has remained an iconic timepiece for more than 60 years. This year, Omega is adding new stainless steel models in to this iconic dive watch collection.

The new models are thinner than previous versions thanks to the new sapphire glass, and they will include plenty of vintage tributes and a brand new Master Chronometer upgrade.

The new collection follows the spirit of the original models. Each of the 41 mm timepieces will be delivered in classic stainless steel, with thinner bezels crafted from an oxalic, anodized treated aluminium for increased hardness.

The bracelets are also in stainless steel and now come with an improved fit and finishing. Their shape has been ergonomically adjusted with streamlined fittings and a thinner, polished-brushed clasp. On the leather straps, a new buckle has also been included.

Perhaps the most noticeable changes can be found on the new dials. For this, OMEGA has utilised a sandwich concept, including a base layer with Super-LumiNova and a second plate over the top with cuttings for the recessed hour markers and numerals. In a nod to history, these numerals are in the vintage Arabic open style, which appeared on early Seamaster 300 models in the 1960s.

OMEGA has also reintroduced the popular lollipop central seconds hand for the stainless steel models, with its tip now filled with Super-LumiNova.

The hand works beautifully with the cleaner dial, which features only the OMEGA logo and Seamaster 300 name. There are no longer any references to the movement (these have instead been moved to the caseback).

The slim inner frame has given the dial a larger display, with an opening of 30.4 mm, as opposed to the previous 29.5 mm. Furthermore, OMEGA has achieved a slightly slimmer Seamaster 300 thanks to a new domed sapphire crystal on the face of the watch. This thinner look is enhanced by the addition of a new conical crown at the side of the case.

Finally, the caseback includes a wave-edged design, as well as a sapphire crystal that offers a view of the OMEGA Co-Axial Master Chronometer Calibre 8912. The movement and full watch have been certified by the Swiss Federal Institute of Metrology (METAS) at the industry’s highest standards of precision, performance and magnetic resistance.
