All diver’s watches have some common features to make their diver’s watch: one-way rotating watch box to ensure that the screw crown is higher than the typical water resistance. These dives watch, however, an extra mile (or measurement), with the use case can drop to 3000 or 4000 meters, the timer can be built in their incredible depth, depth and high-tech equipment to their mechanical movement. Below, let’s take a look at these “extreme” seven diving watches from the package and the difference between them.

Rolex Sea-Dweller Deepwater Water-resistant 3900 meters (about 13,000 feet), it is more than 10% slender than would otherwise be developed due to special circumstances of the development of Rolex. It consists of three compressive elements: 5.5mm thick sapphire crystal, 3.28mm thick caseback five made of titanium, and an inner ring (two rest) biodur-108 steel made. Last summer, Rolex launched the new Rolex Deep Sea D-Blue Edition, and a proprietary “D-Blue” dial dark blue top, bottom, and then gradually darkened.

The 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.

The Blancpain X Fathoms watch combines elements of its famous Fifty Fathoms ancestor with a modern mechanical depth gauge. Though “only” water-resistant to 300 meters, Blancpain calls it the most high-performance mechanical diving watch ever made, with several world firsts, including:

– Measures depth up to 90 meters
– Maximum depth reached memory
– Separate indication on the 0-15m scale with an +/- 30 cm precision
– Retrograde 5-minute counter for decompression stops

The 55.65-mm case, made of satin-brushed titanium, is water-resistant to 300 meters. It features a helium decompression valve for saturation diving and the characteristic unidirectional rotating bezel. The strap comprises 14 articulated parts to ensure a perfect fit on the wrist.

The Ball Engineer Hydrocarbon DeepQUEST has a water-resistance of 3,000 meters, achieved by crafting the entire case out of a single block onto which the bezel is directly screwed. The crown seals, generally considered the weak point of a watch in terms of water resistance, have been strengthened to prevent entry of water when in the screwed-in position. The watch also has a nonreflective sapphire crystal with its thickness raised to 5.3 mm and an automatic helium-release valve.

The Deep Blue Depthmaster 3000M, as its name suggests, is water-resistant to 3,000 meters. The watch is powered by the Japanese Miyota 9015 automatic movement. The 49-mm stainless steel case features a helium valve with a protective cap. The sapphire bezel is filled with Super-LumiNova and the domed sapphire crystal is 6 mm thick.

Requiring 18 months of research, development and testing to complete, the Hublot 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.

The UTS 4000M Professional Diver, another timepiece water-resistant to 4,000 meters, comes in a 45-mm case crafted from a single block of stainless steel. The 6-mm thick sapphire crystal is glued into the case and is also secured by a stainless steel ring with seven hex screws.
