Just like its predecessor, this special edition features the names of shipwrecks and other historical artifacts discovered or explored by NUMA engraved on the caseback, creating a tangible link to maritime history and adventure.
  
Capped by a scratch-resistant sapphire crystal with anti-reflective treatment, all diving-related displays feature a Super-LumiNova® luminescent coating to ensure excellent legibility during dives where visibility is reduced. The watch face is protected by a scratch-resistant sapphire crystal with an anti-reflective coating, and all diving-related displays are coated with Super-LumiNova® for optimal readability during dives in low visibility conditions.
 
Equipped with a Swiss automatic movement with exclusive DOXA decorations operating at a frequency of 28,800 vibrations/hour (4.0 Hz), this watch offers a comfortable power reserve of approximately 38 hours. A date window at 3 o'clock and a screw-down crown round off the package, which is water-resistant to 300 meters (~984 feet), allowing safe exploration of the depths.
 
The watch comes with both the famous ‘Beads of Rice’ metal bracelet in aged steel just like the case, and a sportier, lighter black FKM rubber strap. Both feature a folding clasp with wetsuit extension.
 
Each piece is discreetly and individually engraved with its exclusive serial number as one of 93 watches (XX/93) on the inside of the lugs. Worn on land or at sea, this 42.50 mm-diameter watch, water-resistant to 30 ATM (equivalent to 300 meters or 984 feet), embodies the spirit of intrepid exploration and the timeless allure of adventure. A portion of the sales from this special edition will be donated to NUMA.
