Oyster watch was born in 1926, which is an important step in the history of development of water-resistant watches for replica rolex watches. For this innovative chronograph, "Oyster" is in the name of the apt. A year later, Mercedes Gleitze wore Oyster wrist watch successfully swam across the English channel. Following in the footsteps of rolex founder Hans Wells madoff, many manufacturers have launched their waterproof sporty wrist watches.

The original Mido Aquadura crown cork seal system has been proved to be very effective, even now helium valve or other such technological inventions, its principle foundation is also consistent.

Modern divers watches waterproof depth can reach at least 100 meters, its salient features are: even in the darkness of the underwater environment, the disk is easy to identify, which thanks to luminous Numbers, scale, and pointer; Equipped with one-way rotary watch bezel to make it convenient for the divers segmental decompression. Whether war frogloks commandos, or observers of Marine in peacetime life, they face extremely complex and hostile environment, thus for security reasons, wearing the wrist watch must comply with the strict specification.

Exploration technologies in depth

It seems to be in a twinkling, wrist watch waterproof performance limits has breakthrough to the point of eye-popping marvel at. Now diving deep under the sea world of 1000 meters deep is not difficult for the diving watches, even close to 1960, Professor Jacques picard’s long journey to the bottom of the sea 11000 meters is not extravagant hope. Obviously, divers can't go to the deep sea, with hands-on experiments to prove outstanding technical strength of the watchmaker; But for the corresponding, its advanced measuring equipment developed inspection certificate.
