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.
