The god of the sea is back!
The new SUB 300T Divingstar “Poseidon Edition” recreates one of the rarest 1970s DOXA for a new generation of divers and watch lovers
The 1970s were the golden age of scuba diving. The godfather of diving was bringing subaquatic wonders into living rooms on TV, the sport’s popularity was booming, and countless people were inspired to try diving. Better equipment was making it safer and more accessible and commercial jet travel allowed divers to explore the far corners of the world’s oceans. Scuba diving was the ‘extreme sport’ of the decade, long before that term was invented. Divers strapped life support to their backs and descended, weightless, into an alien world.
It was also a time when a wristwatch wasn’t simply an accessory—it was a vital piece of gear, as critical to safe diving as a depth gauge or breathing regulator. And the dive watch to have was a DOXA—purpose-built, rugged, and trusted to keep track of time underwater. The godfather of diving himself DOXA. So did SEALAB divers and the French Navy. While dive watches had already become fashionable by the 1970s, DOXA stayed close to its diving brief, with its signature oversized minute hand, bright legible dials and patented bezel, printed with the US Navy’s no-decompression limits scale.
DOXA was best known for its trio of SUB 300T dive watches with iconic orange (“Professional”), black (“Sharkhunter”) and silver (“Searambler”) dials. But there was also a short-lived version with a bright yellow dial, known as the “Divingstar” and its rarity has made it a coveted find for vintage watch collectors. An even rarer version was the SUB 300T Divingstar created in partnership with the Swedish dive equipment company, Poseidon. The watch had all the standard features of other DOXA diving watches, but added the black and yellow Poseidon logo to the lower left quadrant of the yellow dial. It was a fitting collaboration, as both brands were on the cutting edge of dive gear development.
Poseidon Diving Systems AB was founded in 1958 in Gothenburg, Sweden, by Ingvar Elvström. Since their introduction in the late 1940s, breathing regulators consisted of two hoses joined at the mouthpiece. This made for a heavy, unwieldy setup that limited a diver’s mobility. Poseidon introduced an innovative new regulator design that had a single hose, and it revolutionized scuba diving, setting the standard that almost all regulators followed, even to the present day.
Poseidon’s Nordic roots meant that it was well-suited for developing gear designed for the unique rigors of cold-water diving. The Cyklon regulator was one of the first to feature a sealing system to prevent freeze-up in cold water, which could result in a dangerous free-flow and rapid loss of air. The company’s neoprene Unisuit became the preferred exposure protection for divers exploring under the polar ice or the deep wrecks of the North Atlantic for most of the 1970s and ‘80s. More recently, Poseidon has turned its efforts to innovating closed-circuit rebreather units for recreational divers, bringing this previously expensive and complicated technology to wider use.
Introduced in 2018 and sold out within 24hours
With the DOXA SUB 300T Divingstar “Poseidon Edition”, these two great diving names are once again joined on the dial of a watch that symbolizes rugged innovation and underwater adventure. The watch resembles its 1970s forebear but is updated for a new era with some modern features. The crystal is now highly scratch-resistant sapphire. The self-winding movement inside is the well-proven Swiss ETA 2824-2. And the watch is now water resistant to 300 meters, the same depth rating of the original SUB 300T. Dial markings and hands are coated with layers of Super-Lumi-Nova™ for optimum long-lasting legibility in dark and murky conditions. The steel bracelet fitted to this special watch is DOXA’s iconic “separate beads of rice” style, with solid end links and a fold-over clasp with an extension for use over a thick diving suit.
The SUB 300T Divingstar “Poseidon Edition” features a helium escape valve on the left case flank, which allows trapped helium inside the watch to evacuate during decompression in a diving bell. DOXA pioneered the helium escape valve in the late 1960s, when it was used extensively by commercial and military divers living for extended periods in underwater habitats, and was the first brand to offer it publicly on a watch.
Only 500 of the DOXA SUB 300T Divingstar “Poseidon Edition” will be made, and sure to be as sought after as the 1970s original. This iconic diving watch is a reminder of the golden age of scuba diving and a worthy companion for adventures in years to come.
