About this watch

A rare find, this handsome Omega Seamaster 600 sports an attractive black dial with Tritium indices. The infamous Seamaster emblem can be found on the watch crown and strap buckle, with the embossed Seamaster hippocampus on the back of the 34 mm watch case.

Reference number 135011, it is powered by the 17-jewel calibre 601 manual wind movement, which beats at 19,800 beats per hour (5.5 per second), and has Incabloc shock protection and sweep seconds.

This lovely circa 1966 piece comes fully regulated, and is in good working order.

A little history: the Omega Seamaster was launched in 1948 to mark the brand’s 100th anniversary. Inspired by the waterproof wristwatches made for the British military at the end of WW2, the Seamaster was designed as a hardwearing yet refined watch for active types. This epitome of understated elegance has since graced the wrists of famous divers, royalty, and even the occasional fictional spy.

The ‘600’ in the Seamaster 600’s name derives from the calibre 6xx (601 in this case) hand wound movement with which it came.
