When it comes to vintage dive watches, few have more presence than the massive professional series Omega Seamasters from the 1960s and 70s. Developed in the late 60s to meet the needs of commerical divers as well as amateurs partaking in the ever-expanding sport of SCUBA diving, these titanic steel tool watches have become icon of design in their own right - and the blueprint for many a modern homage.

We're not going to lie to you and tell you this is a piece you would want to wear every day or that it pairs well with a three-piece suit. We're not going to tell you that the ladies will love it (they don't). But we will tell you that this is one hell of a diver's watch, and you aren't likely to find one in this condition from its original owner again soon. If you fancy yourself a collector of serious tool watches, this is one you shouldn't pass up!
