Details

The Seamaster 300 was Omega's response to the Rolex Submariner upon its introduction in 1957.

Featuring a robust steel case with a 300-meter depth rating, a rotating bezel graduated with dive-timing scales, and a metal bracelet with diver's expansion links, the early Seamaster 300 was not only functional a diver that would go on to see use in Her Majesty's Navy, but is arguably some of the handsomest sports watch designs of the past century.

As it evolved, the Omega Seamaster 300 went on to see numerous evolutionary changes, with nearly innumerable variants in a variety of materials and colorways produced in the past 60 years. This fact alone has made the Seamaster Professional line (as it came to be known) so desirable to a large portion of the collector community — simply because they don't all look exactly the same .

One of the watershed design motifs began in the 1990s with the introduction of blue and black “wave” dials popularized by Pierce Brosnan's 007 in the 1996 Bond film Goldeneye. This design language lives on well after the 90s ended in both modern James Bond-themed limited editions and in the core collection.

The watch that we have here, a Reference 2535.80.00, is a GMT-equipped take on the original design, dating to 2012. It features the same 41.5mm twisted lug case design with a sapphire crystal, a signed crown, and a unidirectional rotating bezel with blue aluminum insert, and a lovely luminous 'wave' dial with a matching 'sword' handset and red GMT hand.

Housing Omega's Calibre 2628 automatic GMT movement within, this piece comes fitted to  the stainless steel multi-link bracelet with a signed clasp - which, in our opinion, is aging extremely well.

This piece is modern, yet nostalgic all at the same time. A not easily achieved combination.
