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.

This example, a Reference 2538.20.00, is a GMT-equipped take on the original design dating back to circa 2004. It features the same 41mm twisted-lug case design with a sapphire crystal, a signed crown, and a bidirectional rotating bezel with an aluminum insert displaying a 24-hour scale.

Nicknamed the ‘Great White’ by collectors due to its ‘wave’ pattern textured white dial, it features luminous hour indices with black surrounds, a matching luminous ‘sword’ handset, a red ‘spear’ GMT hand, a lollipop seconds hand, and a date indicator at 3 o’clock. 

Powered by a self-winding Omega Calibre 1128 movement, this piece is fitted to a multi-link stainless steel bracelet equipped with a signed push-button deployant clasp and a handy diver’s extension mechanism for those seeking adventure abroad with a wetsuit donned and a SCUBA tank in tow.

From the 1990s on, the Seamaster 300 GMT was one of the sports watches offering a local jumping hour hand within a clean, unassuming design, serving as the value-packed compatriot to the Rolex Explorer II 'Polar'. 

Thanks to more accessible movements with ‘flyer’ functionality, GMT options are now much more plentiful. Sure, you can go ahead and buy a new shiny thing, but if you’re been on the hunt for something properly neo-vintage with a cult following all its own, you've found it with the Great White!
