Available on the market today diving watchs number of models, their waterproof ability, from the basic number of 10 meters depth, to the deepest of 11,000 meters. Not all marked with a waterproof watch can go diving. Waterproof 30 meters or 50 meters of the dive watchs, only water-based life, that when it rains can wash their hands or do not take off, try to watch with this level into the pool is unwise. More than 100 meters can be called a dive watch. Marked the 100 meters or 200 meters waterproof watch, you can wear swimming or diving in the diving area. In general, human nature without the aid of tools dive diving world record is now 162 meters, so water resistant to 300 meters above the watch for scuba diving, deep sea diving is a truly professional watches. Any of a waterproof watch, even if labeled water depth, and do not put hot water - watch to water, but not against steam.
Major watch brands seem to have specialized addiction, though most people have no opportunity to dive to 50 meters below, but the brands are still in the efforts to develop a super diving depth. Bvlgari (Bulgari) Diagono Professional diving to 2000 meters expression, Panerai (Panerai) Luminor
Submersible water professional diving watch to reach 2,500 meters, Bo Laishi (Bell & Ross) Hydromax deep-sea diving watch and can even reach 11,000 meters. Many brands have a professional diving watch, water watch depth to make diving much more than a human can dive to the limit.
Deconstruction: the crown and shoulder
Diving into the water watch most likely location is the crown, because the crown is the only part of China Unicom outside and movement. In order to prevent water movement through the crown into the production division tried various methods, a known screw-type crown was designed, the crown can be tightened, the joints crown made of waterproof plastic rubber circle. When the crown was tightened, the water will be strictly isolated from the watch outside. Although screw crown and reliable, but very inconvenient to use, the only problem is that threads will be worn, so that water is decreased. This is today widely used brand Diving crown structure, the same design from the classic Rolex.
Protected by the crown cap, increasing water resistance
Other manufacturers have also developed their own unique crown: about 50 years, the U.S. degrees (Mido) designed a special waterproof design of the crown - Aquadura cork crown sealing system, the U.S. degrees of natural cork embedded in the watch crown, ensure water resistance. Since it is a cork Why not afraid of aging? The reason is to maintain year-round special treatment makes the cork moist and elastic, even in the crown is not fully under tight circumstances, still waterproof. The only downside is that this structure does not guarantee the depth of water, only 50 meters or less waterproof. Last year, the commander of gold limited edition, the U.S. level meter from the spirit of excellence in 1959, which implements the functionality and reliability of the perfect unity, gold edition watches to celebrate the 50th anniversary of the listing of the new limited series. Integration of case no back cover, using a unique Aquadura cork sealing system, built-in waterproof device to the crown cork to ensure water resistance. Although only 30 meters waterproof, but it is the highest daily waterproof guarantee. Panerai locking lever designed to bridge the crown structure, and in 1956 obtained a patent. Principle is there by using a lever to press the case on the crown, so watch significantly enhanced waterproof, waterproof proven able to withstand pressure of 1,000 meters. So far, this device is still one of Peinahaite some signs, Luminor's watches are also suiwatch for left hand operation left the crown. Compressor product family, manufactured by the crown, with product R & D compression screw device to compress the space by rotation, so that the seal inside the crown to reach a complete watertight condition, and thus improve the water resistance. The design of red and white arrows, white arrows represent the crown has been locked, the red arrows represent the crown has been unscrew. In addition, Cartier Pasha Series crown, and Hamilton's divers dive watchs crown, are installed with enhanced waterproofing and protection of the screw-type crown, and to a buckle body linked to the watch, prevent accidental drop loss.
Mido's navigator watches crown sealing system uses Aquadura
People may think that this construction only to watch shoulder decoration and design, in fact for the diving watch, the shoulder is meaningful. It can protect the crown from external influence. Screw locking crown despite pressure than normal-in the crown is more durable and waterproof, but still in use because of friction and external migration, or occurrence of damage incurred. Shoulder have played a protective effect, the current shoulder in two, wrap-style and non-wrapped style. We generally see a non-wrapped style, the crown next to the partition function can play a crash. Another wrap-sucked wrap the whole crown, the crown is an activity of the device sealed, so the crown can not pull out, to achieve the anti-collision purposes. Panerai's crown shoulder pad is very well-known, much to the crown an external locking device, either crash can prevent accidental touch the crown, this case is extremely critical for the wearer, especially in turbid water next. Another example is the Omega Ploprof coaxial dive watch, this is a very complex moment of 70's famous left-handed version of the professional diving watch, then the French mining company had to use Comex submarine was 600 meters waterproof, the new is up to 1,200 meters. A large crown on the left shoulder, the original design when the loose crown, lateral protection device will bounce the square, then pull out the crown, can quickly adjust the date in the first paragraph, second paragraph of the adjustment time . If we protect the device onto the square, you can lock into the case to the crown.
Deconstruction: the inner rotating bezel and
Rotating inner ring has been the nations of the patent
Divers prefer the back a small amount of oxygen tanks, in order to reduce the weight of water, but the amount of oxygen and oxygen bottle size, and therefore people are familiar with diving equipment measuring oxygen device, dive watchs reinforce this need timely . Rotating outer ring can be said that the best features of diving watchs, serve to remind the role of diving time. Annotation scale rotating bezel for the 15,30,45, as most divers can only insist on the oxygen bottle 45 minutes, there is marked individual 60-minute scale. The first 15 minutes with a color or a particular identity, because divers will strictly follow the rise for 15 minutes to do the safety stop, to the absorption from the nitrogen cylinder in the fully released. Usually as long as rotating bezel diving to 0 scale on the bezel align the minute hand, and then after watching the minute hand moving around the scale corresponding to the watch circle can know the time spent diving. Of course, you can also use the countdown to first know your dive time, rotating bezel to align the minute hand minute scale, and then went to 0 scale of the time the minute hand exactly is your time, to that position 0 is the scale of your dive Limit time.
Still vysha Diverscope JR1000 Goldwaters Diving Rotary watch, rose gold ring scale can display the last 15 minutes of diving time
External rotating bezel is designed into a single counter-clockwise, it is time to ensure that only the accounting calculation much less without accounting to prevent the misuse extended time out of danger. Scale and the figures are professional fluorescent coating, easy to dim lights in the water when a clear display. In recent years, new built-in watch circles do not have restrictions on the direction of rotation, because the control bezel crown at the water watch must be locked before. Such as the nations of the Aquatimer Cousteau, built-in stopwatch lap to protect the tips role, without additional holes on the case. Another advantage is that the water watch after the loop without the need to remove the sediment within the joint case. In fact, 1,000 people may buy a dive watch only five have the opportunity to dive to 50 meters of water, compared to the nominal that figure, the more players love is when rotating bezel sharp falls the sound. Omega's Ploprof rotating coaxial Scuba Case attached to the right side of the outer ring to the top of the orange button to control, both can rotate clockwise or counterclockwise, which can be bi-directional rotating dive watch design of the outer ring is more rare . In fact, no ring on the watch can display their craft, but the 50 series of Blancpain watches unique individual rotating bezel. Designers using sapphire crystal cover on the fluorescence scale on (rather than ordinary high-tech ceramics), but also spent several years of effort in particular developed a fluorescence scale adhesive material and metal bezel and sapphire ring adhesive sheet, and applied for a patent. PVD Rolex patented technology is used to fill rotating bezel platinum, due to be issued with a new blue light emitting material, so that the triangle on the outer scale zero instructions visible at night or longer deep-sea .
Deconstruction: Luminous
The luminous effect Diving
All diving watches are equipped with eye-catching luminous pointer and scale, it is because deep-sea divers often find themselves in the dark, so dive watch pointer, scale or surface is usually coated with fluorescent material, and deliberately enlarge the size of a pointer and scale, so that the user is more easy to read time.
Early radium luminous material (Radiomir), because of its contained excessive radiation was discontinued. Luminous material most commonly used now have Super-LumiNova and tritium trachea. Super-LumiNova is a new material, which absorbs light in the gamma particles Chu, sustainable light were more than 10 hours, but the intensity of light after a certain period will have a decay. Tritium tube tomorrow night (also called "gas lamps") is a major modern luminous technology leap. Trachea is the use of tritium Ball (Ball) in the glorious tradition. Advantage is not only self-luminous, high brightness, and long life - life is said to be over 25 years. Principle is the inner wall coated with phosphorescent material mineral glass tube filled gaseous tritium B-rays excited by tritium reaction phosphorescent material cold light source, this source is not bright light and heat divergence, it will not burn and explode. B-ray tube can be cut off, as long as the tritium tubes do not break it on the sound. Tritium does not need external tracheal external light source to provide energy or reflection, can remain swatch and long-lasting light-emitting 10 to 20 years. Tritium tube watch the night out in the shell of the back cover are letters with 3H illumination also mbmicrotec marked, all the watches in the Boer pointer and scale, there are a tritium tube tomorrow night (also including the temperature and second hand). The only bad this is, the pointer would be more heavy, especially second hand, it should be on the watch to go a little impact, in order to maintain balance, Boer watch the second hand has a "long tail", or two RR form a "tail flower." Panerai Radiomir dial luminous effect is through the tag and indicators on the smear layer of special coating to achieve, this coating is zinc sulphide, radium bromide and the new mixture of thorium. This invention and deployment by the Panerai is Florentine before compounds produced by targeting and observation of a distinctive feature of the instrument. Makes the instrument a powerful glow totally dark environment in borrowing may not find the enemy auxiliary lighting to illuminate itself.
