Aquadive remains a company devoted to the same codes as it did in the 1960s and ‘70s—robust, highly water resistant, accurate dive watches for adventurers.
If a scuba diver stays too long at any given depth, it can be dangerous, or even fatal. So keeping track of time and depth underwater is vital. When the Model 50 was introduced in 1970, it put both pieces of data on one wrist, one of the first watches to do so.
