For Buy Rolex Replica Watches, the water, dust, magnetic and vibration are affecting the accuracy of the enemy. In these, waterproof and belongs to the most important because daily use are likely to enter the water watch inflicting great harm. Most of today’s sports watch almost every 100 meters of water, while the diving watch with more than 200 meters of water resistance. However, if we look at the history of the watch waterproof performance, will find that today we take for granted waterproof performance, in fact, this development is a long journey, it is worth slowly taste.
If the beginning of the water watch, that is, in the 1920s, the watch case from withholding changes become screwed. Prior to screwed, waterproof watch solution is sealed within a housing, so although you can protect all the parts, but there are two drawbacks. The first is the volume of the entire watch only lead to very large. The second flaw is the manual movement whenever the need or the chain need to adjust the time when the need to remove it and then put it back from the housing. Then self-winding mechanical watches had not been invented, so this case is, repetitive use regularly, and will wear quickly broken, then repaired. Thus, the future of such housing is limited. Therefore, technicians need to invent a more practical, more durable solutions.
The first attempt was screwed case is a named Francois Borgel have manufacturing technicians, respectively in 1891 and 1903 made two slightly different case using a rotary locking. The main advantage is abandoned shell simultaneously achieved a better seal. The mechanical structure of this case contains a threaded ring, bezel and rear cover is connected with the case by way of the rotation lock. This case also has some drawbacks, because the crown has not been sealed, moisture and fine dust can still enter into the movement.

The first patent on the crown seal was born in October 1925 from Cheap Rolex Replica Watches Paul Perregaux and Georges Perret two watchmakers, but the distance is still fully mature technology is far worse. It also has two major drawbacks. First, loosen the crown and on the chain position is the same, so once you put everything set up, if you unscrew it again, watch springs will certainly be some wear and tear. Second, the material used to seal the crown exposed position on the outside (16 positions), and the use of fragile materials cork, leather, felt, or the like, these materials can easily lose the sealing properties and then need to be replaced. The production capacity at the time, these are the only materials that can be used.
In this patent is one of Rolex founder Hans Weiss ? Dov (Hans Wilsdof) discovered and after the buyout, has been improved. Moved from the housing outer shell seal and seal the material selection with lead, extending the usefulness and waterproof effect is very ideal. Improved conditions in the Rolex crown design, the classic Rolex Oyster case also bred. Dov Weiss used his name registered in the United Kingdom to the patent, which is notorious diving watch originator – Oyster patents. Since then, the technology cooperation with Rolex diving watch out shocked the world.
The first diving watch rotating outer ring is the emergence in 1953, Blancpain launched the first generation to whom the Fifty Fathoms diving watch equipped with a rotating bezel, and also applied for a patent for this. The most famous Rolex “Kelpie” series is to wait until the end of the patent protection of rotating equipment in the 1980s of the outer ring. And may double entry rotating bezel different dive watches can only unidirectional rotating bezel counterclockwise rotation, which is to protect the lives and safety of the diver setting to prevent divers underwater complex situations caused by misuse rotating bezel, extend dive time.
Luxury Rolex Replica Watches
In 1982, the international standard diving Luxury Rolex Replica Watches formally established by the ISO, after two amendments. It identified 11 major items, including watches can withstand 100 meters of water; in the dark can still be clearly identified; anti-magnetic ability; having shock resistance; resistance to external resistance; salt water; temperature difference Decorating; accurate to at least have 5 points scale rotating bezel; in the water affect the operation and use; resistant to pressure; to add helium diving watches, you must pay attention to the timing of the normal risk of impaired function and so on.
In addition to screw-in case, crown and rotating bezel on the case there is an important water technology – helium valve, when diving tanks mechanical diving, deep sea due to the high pressure helium gas into the case, this gas flowing pressure will watch with the outside world was flat. But when diving tank rises, the inner pressure of the gas will be much higher than the outside world, which would open the case facing the danger of explosion. The helium valve (now the vast majority of the watches are automatic helium), you can put the case backlog in the helium shell quickly discharged outside the case to ensure safety.

In general, the helium valve equipped dive Swiss Rolex Replica Watches can be qualified deep-sea fishing, and for diving enthusiasts often play ordinary “scuba” diving (helium is carrying oxygen bottles diving), or without the aid of any instrument “naked when latent “diving watch means there is no need to install helium, because the limited depth of the dive.
In addition to these, diving watch material, watch mirror, bracelet, and so the movement is carried out continuously with upgrades. Although these expensive advanced dive watches to your hands, mostly hard to show their skills the seabed. But these marked diving depth timing tool, its excellent professional quality no doubt. Like a diving watch just its appearance as well as the story behind it, and the sea of infinite yearning.
