100 Years of the Oyster: How a Shellfish Changed Watchmaking History
Have you been following the Watches and Wonders exhibition lately? This year, Rolex has centered its theme around the "Oyster Story." It’s a fitting tribute, as 2026 marks the 100th anniversary of the legendary Oyster case.
This design didn't just change the brand; it redefined the history of the wristwatch. Here is how a century-long legacy began.
The story actually begins in 1925. Two German artisans, Paul Perregaux and Georges Peret, invented a sealable crown mechanism. Using a system of springs and tubes, it was designed to keep moisture out of the case. While it seemed like a niche mechanical tweak at the time, it became the foundation of the waterproof watch.
Hans Wilsdorf, the visionary founder of Rolex, saw the potential immediately. He acquired the patent and pushed the concept further, asking: “What if the entire watch could be hermetically sealed?”
Legend has it that the breakthrough happened during a dinner. While Wilsdorf was prying open an oyster, he marveled at its biology. Once an oyster shell closes, it is virtually impenetrable to water. He realized a watch case could function the same way. That single meal changed the course of the industry forever.
In 1926, Rolex officially launched the world’s first truly waterproof and dustproof wristwatch: the Oyster. By combining three key elements, it became as impenetrable as its namesake:
- The Screw-down Crown
- A Sealed Case Back
- A Solid Middle Case
In 1927, the Oyster faced its first real-world "stress test." British swimmer Mercedes Gleitze wore the watch while swimming across the English Channel. After more than 10 hours in the freezing, turbulent sea, the watch emerged in perfect working order. From that moment on, the name Rolex became synonymous with "waterproof."
Fast forward 100 years, and the Oyster architecture remains the backbone of the brand. Whether it’s the Oyster Perpetual, Submariner, Daytona, or Datejust, they all live within the protective walls of that original 1926 concept.
So, the next time you’re enjoying a fresh oyster, will you think about the tiny mechanical marvel on your wrist?
