For sale is a remarkable piece of horological history: a genuine Vintage Oyster Watch Company Oyster Essex from the World War II era. The Oyster Watch Company was owned and operated by Rolex, and during WWII, Rolex utilized the Oyster Watch Co. name to navigate tariffs and import restrictions in certain markets, particularly in the UK and Canada. Because of these regulations, watches were branded Oyster Watch Company instead of Rolex, even though they were manufactured using the same components, built to the same standards, and fitted with Rolex’s patented waterproof Oyster case. While the dial does not display the Rolex name, this is still a Rolex-built watch, making it a highly desirable and historically important piece.

This example features the Oyster Essex configuration and is powered by its original Caliber 59 movement. The watch is currently running smoothly and keeping accurate time.

The watch has aged gracefully and shows signs of use and age consistent with a genuine WWII-era timepiece. The dial, hands, case, and movement are original, preserving its vintage authenticity and strong collector appeal. The original dial features luminous hands and Arabic numerals, delivering the classic vintage military aesthetic. The watch is fitted with an extremely rare NOS era-correct Bonklip bracelet.
