Up for sale is a remarkable piece of horological history: a genuine Vintage Oyster Watch Company Oyster Solar Aqua 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 Solar Aqua. This example is a 17-jewel (17J) version, which is a higher-grade variant than the more commonly encountered 15-jewel Caliber 59 movements. The watch is currently running smoothly and keeping accurate time as it was serviced not that long ago. The watch repair person suggested that I keep the original crystal on it to preserve the originality.

Adding to its historical significance, the caseback features an engraving of initials with his RCAF junior officers regiment service number, giving this watch a direct personal connection to the WWII era and enhancing its appeal as a true military-associated timepiece.

The watch has aged gracefully and shows signs of use and age consistent with a genuine WWII-era watch. 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 a leather strap that gives it a nice clean and vintage appeal.
