The First Ever Dive Watches
A Deep Dive Into History
When you think of dive watches today, images of rugged stainless steel cases, rotating bezels, and luminescent dials come to mind. But the evolution of these underwater tools didn’t happen overnight. Before dive watches became essential gear for professionals and style icons for collectors, they began as innovative responses to the challenge of keeping time underwater. Let’s take a deep dive into the origins of the first dive watches and the legacy they’ve left behind.
Rolex Oyster: The Pioneer That Made a Splash
It is widely believed that Rolex laid claim to create the first dive watch when they released the Oyster in 1926. While not designed specifically for diving, it broke new ground as the world’s first truly water-resistant wristwatch. The Oyster’s case was hermetically sealed with a screw-down crown, caseback, and bezel—a breakthrough that kept moisture and dust at bay.
The watch famously passed its first real-world test in 1927 when English swimmer Mercedes Gleitze wore it while swimming across the English Channel. After more than 10 hours in frigid water, the watch emerged unscathed and fully functional. Rolex capitalized on the feat with a bold newspaper campaign, positioning the Oyster as the go-to watch for reliability and endurance. While not yet a dive watch in the modern sense, the Oyster was the prototype of water-resistant timekeeping.
*Please note that recent claims have surfaced that Rolex may NOT have been the first dive watch ever invented*
Blancpain Fifty Fathoms: Birth of the Modern Dive Watch
Fast forward to 1953, when Blancpain revolutionized the watch world with the release of the Fifty Fathoms, widely considered the first purpose-built dive watch. Unlike the Oyster, this timepiece was specifically engineered for underwater use and professional divers. Its development was spurred by a request from French Navy combat swimmers, including Captain Bob Maloubier, who needed a reliable, legible, and durable watch for military operations.
The Fifty Fathoms delivered on every front: it featured a unidirectional rotating bezel for tracking dive time, high-contrast luminous markers for visibility in dark waters, and an automatic movement to reduce wear from winding. With a water resistance of 50 fathoms (about 91 meters), it set a new benchmark for what dive watches could do. It was more than a tool—it was the blueprint for generations of divers’ watches to come.
Rolex Strikes Again: The Submariner Surfaces
Just months after Blancpain made waves, Rolex released the Submariner, solidifying 1953 as a landmark year in dive watch history. The Submariner built on the Oyster’s waterproof foundation but added dedicated features for diving, including a rotating bezel and improved water resistance, eventually reaching depths of 100 meters and beyond.
With its sleek design, durability, and strong ties to professional diving and pop culture (thanks to James Bond), the Submariner quickly became a legend. Its design has remained largely consistent over the decades, proving the strength of Rolex’s original concept. While Blancpain may have launched the first dive-specific watch, Rolex helped turn the category into a lasting icon.
Enter Zodiac: Bringing Dive Watches to the Public
While Blancpain and Rolex focused on military and professional use, Zodiac saw an opportunity to bring dive watches to the everyday adventurer. Also released in 1953, the Zodiac Sea Wolf was one of the first dive watches marketed directly to civilians. It featured robust water resistance, a rotating bezel, and a more affordable price tag, making it accessible to recreational divers and hobbyists.
The Sea Wolf helped democratize dive watches, bridging the gap between tool and trend. It wasn’t just a functional piece—it became a fashion statement and a symbol of adventure, influencing countless brands that followed.
A Legacy That Keeps Ticking
The history of dive watches is a tale of innovation, necessity, and evolution. From the waterproof ingenuity of the Rolex Oyster, to the military-grade precision of the Blancpain Fifty Fathoms, and the mainstream appeal of the Zodiac Sea Wolf, each watch played a pivotal role in shaping the genre. Dive watches today owe their form and function to these pioneers—and their stories continue to inspire new generations of watch lovers, collectors, and explorers alike.
