The DeepQUEST has a water-resistance rating of 3,000 meters.
The 3,000 meter water resistance is achieved largely through a “monoblock” case construction.This means that the entire case was milled from single block of metal, in this case titanium, thus minimizing possible “weak points” that could compromise the timepiece’s water integrity at great depths.
The sapphire crystal is also a very hefty 5.3mm thick.
