In 1970, Aquadive introduced its Time-Depth Model 50, a revolutionary dive watch that incorporated a depth gauge and utilized an electronic movement. It remains an icon much sought after by collectors. We based our flagship Bathyscaphe 300 on the Model 50, with an identical case, but updated to feature a self-winding Swiss automatic movement. Though its burly steel case is rated for 3,000 meters of water pressure, we actually test each case to a crushing 5,000 meters for good measure, making this one of the deepest diving watches in the world.Buy Now
The Bathyscaphe 300 is our most capable watch, with its abyssal depth rating of 3,000 meters that comes courtesy of a steel case CNC machined out of a solid block of German 316L surgical stainless steel.
Should you find yourself in a helium-enriched diving bell, the case is equipped with an automatic gas relief valve nestled between the strap horns at 6:00, in place of the orifice of the old Model 50’s depth gauge.
The bezel is topped with a scratch-resistant and luminescent ceramic timing ring and precisely ratchets through 60 positions, allowing you to time everything from decompression stops to parking meters.
Inside ticks a self-winding Swiss movement, the ETA 2824-2, which drives hours, minutes and sweep seconds, a quickset date function, and is adjusted to five positions for accuracy.
Befitting a capable watersports watch, the Bathyscaphe 100 comes fitted with a 24-millimeter ISOfrane rubber strap with stainless steel Aquadive-signed buckle.
The Bathyscaphe 300 is limited to 500 pieces and the individual number is engraved on the caseback.
