Dive watches have become the default choice for a solid everyday watch, collectors becoming spoiled by what only a few decades ago were record-breaking specs. The story of the dive watch actually begins in 1953 when Blancpain’s Fifty Fathoms became the first watch rated to 100m. That same decade, Jacques Cousteau’s adventures captured the world’s imagination, turning the mysterious blue depths into a playground for a new breed of explorer. By the 1960s, recreational diving had exploded, and watchmakers found themselves in a deep-sea arms race to create the first dive watches to achieve historic water resistance milestones.
With each year leading up to the millennium, watches aimed to push further below the surface. Mechanical courage made metal. Ironically, actual professional divers began using wrist-worn dive computers, as the mechanical tool watch became relegated to a backup. But still the quest to go deeper continued.
Today’s top-specced dive watches can all dive way deeper than the human body will survive. The limits of human endurance beneath the sea are unforgiving. Somewhere between 305 and 457 metres (1,000–1,500 feet), the body begins to lose its battle with pressure; push further, and the abyss wins. Around 396 metres (1,300 feet), the lungs would simply collapse. By 335 metres (1,100 feet), survival is no longer a test of courage or strength – it’s a 99% certainty of death. For context, that’s still a fraction of the depth today’s purpose-built dive watches is designed to withstand.
100m: Blancpain Fifty Fathoms (1953)
The Blancpain Fifty Fathoms wasn’t just the first true dive watch – it defined what a dive watch is. Although that claim is somewhat controversial as it’s debated if the Fifty Fathoms or Rolex Submariner actually came first. Created in 1953 (possibly 1954) for the French Navy’s “Nageurs de Combat,” the Fifty Fathoms combined a rotating bezel, high legibility, and 100 meters of water resistance in a purpose-built design that revolutionised horology. Its name, “Fifty Fathoms,” was both poetic and precise, a mariner’s measure equating to 91.44metres.
Beyond its military roots, it ignited a civilian fascination with the sea, inspiring generations of watchmakers and adventurers alike to follow Jacques Cousteau into the deep blue. Today the Fifty Fathoms remains a strong contender but has long since transcended its tool status. The dive legend starts at around £15K, still bulletproof with its signature sapphire bezel, but with a price that for many precludes it from the tough job it was meant to do.
200m: Rolex Submariner (1959)

The Submariner was already an icon when Rolex doubled its depth rating to 200 metres or 660ft in 1959 with the ref. 5512. And if your granddad was a pro diver back then, chances are his scratched Submariner will now be worth more than your car. Their value today elevate these watches far from their original purpose and into grail watch territory, as seldom used safe queens. However, in its day, it simply represented both engineering confidence and the maturing of underwater exploration, a time when the Rolex Professional series was, in fact, intended for professionals. With its screw-down crown and Oyster case, the Submariner became the blueprint for virtually every dive watch that followed, with countless copies and homage watches emulating its signature soft crown guards and broad-shouldered look.
For decades the Rolex Submariner was the professional’s companion from coral reef to command post, and a symbol of waterproof perfection that defined an era. These days, unless you’ve been living under a rock, the chance of walking into the new Rolex flagship store on Bond Street and buying one is slim. But that doesn’t detract from its stature, and a well-deserved image as the sports watch to end all sports watches.
500m: Aquastar Benthos (1970)
The first watch to become certified for a dizzying 500m was an Aquastar, a cult brand now revived with a great catalogue of retro-infused sports watches. As dives went deeper and commercial exploration grew, Aquastar launched the Benthos 500M, the world’s first watch rated to 500 metres. Its monobloc case and domed crystal offered unmatched strength, making it a true diver’s instrument.
The Benthos blurred the line between science and sport, marking a shift from adventure to professional utility beneath the waves and as many brands went through troubled times in the seventies and eighties. In its new iteration, former Doxa revival strongman Rick Marei has recreated its sixties icons, and the watches now offer a period perfect taste of what real pros wore back in the day.
1,000m: Jenny “Caribbean 1000” / Ollech & Wajs Caribbean (1964)
In 1964, Jenny’s “Caribbean 1000” rewrote the rulebook. Certified to 1,000 metres, it was the first wristwatch to breach the kilometre barrier, achieved through a revolutionary one-piece case design. This innovation was shared with Ollech & Wajs, giving rise to a family of indestructible tool watches that captured the spirit of saturation diving and Cold War-era deep-sea ambition. The Jenny wasn’t just a watch – it was a pressure-proof statement of intent, and today still offers great value if you find one.
For a modern recreation you have the Ollech & Wajs C-1000 A, which pays tribute to that original design and still sports a 1,000m water resistance rating. It’s even comparatively small for a deep sea dive watch measuring 39.5mm in diameter, though balanced by a 15.8mm thickness.
11,000m: Rolex Sea-Dweller Deepsea Challenge (2012)
Half a century later, Rolex once again reached for the depths with the Deepsea Challenge, rated to 11,000 metres. And while the irony might be felt knowing that no human can survive this depth, it represents the summit of subaquatic engineering. Built from grade-5 titanium and tested to withstand pressures found in the Mariana Trench, it’s less a watch and more an engineering miracle. While few wearers will ever descend beyond a swimming pool, this leviathan serves a higher purpose – a reminder that human craftsmanship still dares to go deeper, chasing the limits of possibility itself.
It famously accompanied James Cameron to those very depths on the outside of his Challenger submersible as a concept watch. Then in 2022 Rolex finally released a production model in titanium and which has a £23,450 price tag.
