According to the knowledge of general watch fans, the so-called ‘high-performance’ diving watches will be equipped with helium discharge devices, so that helium that enters the watch body from the gap of the watch due to high pressure in the deep sea can be eliminated. Avoid the risk of rupture due to the pressure of the helium gas expanding due to pressure reduction during the process of floating on the surface. In order to overcome the huge pressure in the deep ocean, this type of professional diving watch is composed of a multilayer structure, so the body is usually thicker, which is also a major feature. This article introduces several high-performance diving watches with a water resistance of at least 500 meters. Watch fans can see if they can control them!
ROLEXDeepseaD-BlueRef. 126660 Oystersteel case, Cerachrom ceramic bezel unidirectional rotating bezel, diameter 44 mm, hour, minute, second, date, automatic helium valve, 3235 automatic winding movement, power reserve 70 Hours, Rolex Observatory certified precision timepiece, sapphire crystal glass, waterproof 3,900 meters, oyster steel chain strap, Glidelock extension system.
Rolex launched Sea-DwellerDeepseaD-BlueRef.116660 in 2014, and directed Titanic to James. James Cameron submerged the Mariana Trench in a Deepsea Challenger submarine, setting a world record for 10,908 meters (35,787 feet) of single-person diving in the Pacific Ocean.
The dial with blue and black gradient echoes the color of the seawater in the deep sea, and the Cerachrom ceramic circle plated with platinum numbers and scales by physical vapor deposition method is even more distinguished.

11-layer body structure including the Ringlock system (5.5 mm thick sapphire crystal glass, nitrogen alloy stainless steel ring, oystersteel body, and five-level titanium case back), plus a triple waterproof system watch Crown, waterproof performance up to 3,900 meters.
In 2018, it was equipped with a new 3235 self-winding movement, which increased its power reserve from 48 hours to 70 hours. In addition, the lugs and the sides of the case have been redesigned, and the oyster adjustable glidlock strap has been widened by 1 mm. To increase the comfort of wearing.
ORISDiveControl titanium case, unidirectional rotating bezel, 51 mm diameter, hour, minute, small seconds, date, chronograph, automatic helium discharge valve, Oris774 automatic movement, 48 hours power reserve, sapphire crystal glass mirror surface , Special engraved case back, waterproof 1,000 meters, rubber strap, limited to 500 pieces.
Oris cooperates with Swiss commercial diver RomanFrischknecht to launch the DiveControl Limited Dive Watch, and has specially developed a patented Rotary Safety System (RSS), which can protect the outer bezel with a toothed rubber ceramic bezel through a special locking mechanism to avoid using the watch. When recording the dive time in a circle, or operating the timing function with a precision of 1/4 second, the accuracy is affected due to the omission of any process.
Even though the diameter of the watch is 51 mm, the case is made of titanium, which is relatively light and difficult to control. The black dial with engraved waves and yellow contrasting colors are unique in design.
OMEGAPlanetOceanBigBlue ceramic case, unidirectional rotating ceramic bezel, diameter 45.5 mm, hours, minutes, seconds, date, 24 hours second time, manual helium exhaust valve, 8906 Master Observatory automatic winding movement, power reserve 60 hours , COSC certification, sapphire crystal glass and bottom cover, waterproof 600 meters, rubber strap.
Omega’s PlanetOceanBigBlue, in addition to being a dive watch, also has a practical second time function. It is equipped with the 8906 Master Coaxial Escapement Automatic Winding Movement, which has passed eight rigorous tests of the MasterChronometer (METAS) of the Swiss Federal Institute of Metrology, including performances that can withstand 15,000 Gauss magnetic force.
The manual helium exhaust valve is located at 10 o’clock, and the helium can be exhausted by turning the crown. The blue ceramic bezel incorporates Liquidmetal® (liquid metal) graduations, and the first 15 minutes are embedded in orange rubber, which is quite bright.
Bucherer Plavich Deep Dive Watch Series ‘Black Devil Fish Special Edition’ DLC-coated titanium case, unidirectional rotating ceramic bezel, diameter 44.6 mm, hour, minute, second, date, automatic helium exhaust valve , CFB1950.1 self-winding movement, 38 hours power reserve, COSC certification, sapphire crystal glass surface, special engraved case back, waterproof 500 meters, rubber strap, with PET plastic recycled textile material layer.
Bucherer Plavich Dive Watch Series ‘Black Devil Fish Special Edition’
This year, Bucherer continued to cooperate with the British charity ‘MantaTrust’ to launch the Plavi’s deep dive watch series ‘Black Devil Fish Special Edition’ and donate part of the proceeds from the watch sales to the foundation. Conduct research on manta rays to promote and respond to conservation programs. Through the transfer of the dial and the engraved image of the case back, the watch shows the image of the devil fish swimming in the water.
The titanium case is black-plated with diamond-like carbon and matched with a strap made of recycled PET plastic to reduce waste of resources. It also shows the intention of environmental protection in actual actions.
