The Seamaster is the longest-running product line still produced by Omega. It was introduced in 1948 and was loosely based upon designs made for the British Royal Navy towards the end of World War II. The original Seamaster's key feature was an O-ring gasket used to provide its waterproof seal.

In 1957, when scuba diving was the en vogue sport, Omega rolled out a trio of 'Master' watches - The Speedmaster, The Railmaster, and The Seamaster 300. Unlike its predecessor, the Seamaster 300 was specifically designed for underwater use.

What’s On Offer 

The Seamaster 300 remains a robust-looking watch, even when compared to its modern counterparts. Its substantial proportions, chunky sword hands, and partial Arabics combine to offer all of the hallmarks of this iconic vintage Omega diver reference. This particular 'thin bezel' example is not quite as readily available as its Bakelight counterpart and therefore is very much sought after. 

The lume has aged to a deep coffee colour which allows the beautiful pumpkin colour of the Arabic numerals and Omega/Seamaster signatures to come alive, a brilliant white central seconds hand completes the dial. 

The Omega bloodline runs throughout this watch with the signed dome crown and etched Hippocampus on the case back. The watch is paired with a soft tan strap which certainly brings out the warmth of the dial. 

This is an absolute beauty, really collectable and still very wearable, every vintage watch collector should have one of these in their collection!
