In November this year, Rolex launched a new deep-sea challenge mechanical watch, which broke the record with a waterproof depth of 11,000 meters and became the diving watch with the deepest waterproof depth in the world of famous watches. In addition to the use of a titanium shell, it is named "Titanium Ghost King" among players, with a public price of 203,200 yuan.
This watch has a diameter of 50 mm and a thickness of 23 mm, of which 9.5 mm is a sapphire crystal, with a total weight of 251 grams. One of the highlights of this watch is that it is made of titanium metal, which is light, strong and corrosion-resistant. Rolex's previous watches were made of 904L steel. In contrast, this mass-produced watch is 30% lighter and more suitable for wearing. The "Titanium Ghost King" deep-sea challenger is too big. The size is 50mm, and the thickness is 23mm. If you don’t use titanium, but use a steel case, the weight of this watch is really “unable to wear” on the average person’s wrist. The "Titanium Ghost King" Deep Sea Challenge is the first mass-produced and sold titanium case watch in the history of Rolex.
Rolex has a unique super waterproof structure, the sapphire mirror of the "Titanium Ghost King", which is 9.5mm thick. Sapphire crystal, locked on the "compression steel ring", and uses a titanium bottom cover. When the sapphire mirror of the watch is subjected to huge water pressure, the pressure will be transmitted to the "compression steel ring" and the titanium bottom cover. The compression resistance of the "compression steel ring" is three times that of Rolex 904L steel; the titanium bottom cover has a certain degree of elasticity and can be deformed under pressure. The two work together to relieve and release the water pressure. The other parts of the “Titanium Ghost King” Deep Sea Challenger are the same as the regular Rolex Sea-Dweller and DEEPSEA. There is an automatic helium escape valve on the side of the case, and the crown has a triple lock.
Although the official label of "Titanium Ghost King" is 11,000 meters waterproof, according to the water pressure test of Rolex and COMEX, the actual waterproof of "Titanium Ghost King" can reach 13,750 meters.
