Brand vibe
Aquadive started in 1962 in Germany making honest tool divers for actual scuba divers, hit its peak with the 1970 Time-Depth Model 50 (a depth gauge on your wrist, very cool, very 70s), then slipped under the waves like most cool German watch brands eventually do.
It was hauled back up in the 2010s by Rick Marei (the guy who also revived Doxa and Tropic) and now operates out of Vienna under the Synchron umbrella alongside ISOfrane. The current Bathyscaphe 100 and 300 are faithful re-editions of the OGs: chunky with Swiss guts (ETA/Sellita), 1000m of "abyssal" water resistance you will never use but probably brag about at parties. The kind of slab-handed legibility that suggests the designers spent zero minutes worrying about whether it would fit under a cuff.
If a Doxa feels too orange and a Squale feels too dressy, Aquadive is the third leg of the vintage-revival-dive-tool uh.. stool. Probably of the three it is my personal fave. Particularly the Bathysphere in yellow.

Sourcing & Build
InferredSourcing Notes: Originally founded in Germany in 1962 by Bernhard Bock as a maker of professional dive instruments and watches (the 1970 Time-Depth Model 50 is the most collected). Dormant for decades. Revived in the 2010s by Rick Marei — the same operator behind the Doxa and Tropic revivals — and now produced under the Synchron Watches umbrella in Vienna, Austria, where the Aquadive, Synchron, and ISOfrane brands all live together. Movements are Swiss automatic — ETA/Sellita SW200 (3-hand) and SW330 (GMT). Cases are Swiss-made stainless steel, DLC-coated steel, and CuSn8 bronze. Water resistance is the brand's calling card: the BS100 family is rated to 1,000m, the flagship Bathyscaphe 300 was tested by the brand to 4,850 ft in the Gulf of Mexico on an ROV. Sold primarily through shop.synchronwatches.com.
