Omega Seamaster Professional Diver 300 M 210.30.42.20.10.001
Initially released in 1948 and based on watches used by airmen in WWII, the Omega Seamaster has become one of Omega’s best-known collections. Initially, a dress-style watch with thick lugs, the Seamaster was designed to promote daily wear while remaining functional for use in water with 62.5 meters of water resistance. However, the modern Seamaster that we know and love today was born nine years later, in 1957. This was when the Seamaster 300 was released after Omega was inspired to upgrade the Seamaster after they had 50 Seamaster cases with rubber O-ring gaskets tested in 1955, which led them to work with new materials and push their boundaries. As a result, they created the Seamaster 300, which featured a heavily luminescent dial and handset, a rotating bezel, a thick domed hesalite crystal, and double crown seals. Interestingly, while named the Seamaster 300, the watch was originally only rated for 200m of water resistance, with Omega insisting the watch could outperform the testing equipment. Either way, the Seamaster lives on as James Bond's watch of choice and now enjoys the privileged position in today’s market as one of the most iconic dive watches ever released. Launched in 2022 four years after the new collection debuted, the watch we have here is the ref. 210.30.42.20.10.001– the latest edition of the Seamaster 300m, with the all-new inhouse automatic cal. 8800 METAS-certified movement, a green ceramic bezel and a matching green ceramic dial with wave engravings, and a comfortable green rubber strap. Perhaps the optimal tool watch, this model is a seriously impressive member of the Seamaster stable with its elegantly crafted construction and carefully executed finishing marking Omega’s high-end attention-to-detail. Alongside its rich history, this is certainly a watch one can be proud to own and wear.

THE DIAL
Featuring a polished green zirconium oxide ceramic dial with a wave pattern engraved into its surface, the Seamaster 300M embraces its nautical theme and goes beyond its tool watch utility to offer an aesthetically interesting display.
THE CONSTRUCTION While measuring 42mm in diameter, this example's rubber strap, in conjunction with its downturned lugs, slims the Seamaster 300M down to make it fantastically wearable.
