Welcome to “Watches You Should Know,” a new bi-weekly (the once-every-two-weeks kind) column highlighting little-known watches new and old that have interesting stories or have had a surprising impact on the industry.
The Submariner and Seamaster may be the undisputed kings of the dive watch realm, but there are other, lesser known timepieces that are arguably cooler, and the watch world seems to finally be catching on.

Perhaps the funkiest of these vintage divers is actually a chronograph produced in the 1960s called the Deepstar, produced by a company called Aquastar (we know, we know — lots of “stars”). Aquastar was founded in 1962 by Frédéric Robert, a longtime SCUBA diver. JeanRichard, Aquastar’s parent company, filed a patent in 1958 for a design that would become the brand’s first dive watch, called the Aquastar 60. Retailed under several names, depending on the market, the Aquastar line became so successful that its popularity eclipsed that of the other sub-brands.
Though Aquastar designed and built numerous timepieces, it was the Deepstar that is perhaps most interesting, and in no small part because it is a chronograph. The watch features a roughly 38mm-wide stainless steel case (not including crown or pushers) and a 20mm lug width. It’s powered by a Valjoux 23 manually winding movement driving its signature sub-dials: a running seconds hand at 9 o’clock that floats freely without any actual sub-dial behind it, and an oversize “big eye” 30-minute totalizer at 3 o’clock for recording elapsed minutes.
