It’s rare to find a diving watch with such a reasonable pricetag and unusual looks that’s rated as far down as 800m beneath the surface. It’s even rarer to find one that’s equally at home in the murky abyss as on the wrist of a stylish globetrotter, being kitted out with a second time-zone, power-reserve indicator and scratchproof diamond-like carbon coating.

All the Clerc touchpoints are present and correct – high-tech square-within-a-circle case with lockable bezel and chronometer-rated automatic movement – but with even more into the bargain. Especially notable is the helium escape valve, first pioneered by Rolex in the Sixties, which allows helium atoms that have crept into the watch during bathyscaphe saturation dives to escape, preventing the crystal from “popping” off during repressurisation.


Taking Clerc’s futuristic diving watch concept even further than before, this special timepiece acknowledges that the extreme deepsea diver is likely to hop datelines on a regular basis and therefore in need of a GMT function, as well as the convenience of a power reserve.

In The Know

"... it turns out the power reserve and GMT hands are also lumed… Boy oh boy, do I like having the extra bits of glory." aBlogtoWatch

"It’s important for a divers’ watch to balance its set of crucial functions alongside legibility. In terms of design, Clerc sets itself a decent challenge by incorporating the power-reserve indicator and a 24-hour GMT." WatchTime

"A contemporary design, which could just as easily be interpreted as being as futuristic as something from the world of science fiction." OceanicTime
