All the divers’ replica watches share: unidirectional rotating bezels, secure screw-down crowns, higher-than-typical water resistance. Some of these divers’ watches, however, go the extra mile (or fathom), with cases that can descend to 3,000 or even 4,000 meters, chronographs operable at incredible depths, or high-tech depth gauge devices built into their mechanical movements. Below, we take a look at seven of these “extreme” dive watches and what sets them apart from the pack.
The uk replica Rolex Sea-Dweller Deepsea has a water-resistance level of 3,900 meters (nearly 13,000 feet), and it is more than 10 percent slimmer than it otherwise would have been thanks to a special case construction developed by Rolex. It consists of three pressure-absorbing elements: a 5.5 mm thick sapphire crystal, a 3.28-mm-thick caseback made of grade 5 titanium, and an inner ring (on which both of them rest) made of Biodur-108 steel. Last summer, Rolex launched the new Rolex replica Deepsea D-Blue Edition (pictured below), with a proprietary “D-Blue” dial that is dark blue at the top, and then darkens gradually to black at the bottom.
The uk replica Breitling Superocean Chronograph M2000 has a chronograph that can be operated at a depth of 2,000 meters underwater. The watch is the first to feature a patented magnetic push-piece system, in which the chronograph controls are operated via the metal of the case. Along with the screw-locked crown and the 4-mm-thick sapphire crystal, these pushers enable the wearer to use the watch at the extreme depth of 2,000 meters (or 6,600 feet) without the risk of water seeping in.
Requiring 18 months of research, development and testing to complete, the uk Hublot replica Oceanographic 4000 was the the first diver’s watch able to withstand the pressure exerted at a depth of 4,000 meters, or about 13,120 feet. (Hublot actually tested the seal all the way to 5,000 meters in a Roxer tank.) To ensure the watertightness of the watch and to resist this extreme pressure, the synthetic sapphire crystal is 6.5 mm thick. The screw-down caseback is made of grade 2 titanium. The Oceanographic 4000 has a helium valve, which allows gases that have infiltrated the watch during the descent to safely escape during the ascent.
