Crystal: Sapphire Crystal. Watches made of sapphire crystal have a very high hardness, with a Mohs hardness of 9, which is second only to diamonds. Its hardness is almost 3 times that of mineral glass and 20 times that of acrylic mirrors.
Luminiscence: Hands and Markers. The style of the watch’s luminiscence is hands and markers. The luminous things makes your watch more delicate and high-end.
Watch Case: 316L. The case is the most important part of the watch. 316L steel is a very strong and corrosion-resistant steel. It has the same strength as the most popular grades (HRC52, HRC55), but only half the weight. Compared with competitors, the production cost of stainless steel is also higher.
Bezel Material: Stainless Steel. The stainless steel bezel material is one of the best materials for watches. It is more simple and endurable. It makes you improve your temperament from the inside out.
Dial Markers: Index. A watch is a timepiece that displays the time in an analog form, unlike the normal dial, the watch uses some simple indexs as dial markers to show us what time it is.
Case Back: Solid. Rolex usually uses a solid back cover, which transmits vibrations better than the back of a plastic case.
Band Material: 316L. The band has 316L, which not only directly protects the internal parts of the watch, but also determines the various performance indicators of the watch to a large extent.
Clasp: Fold Over Clasp. This watch case has a designed clasp to make it easier and faster for the user to open and fold the watch case to keep it secure.
Water Resistance: 100 meters. Always wearing the watch even when you are in bathroom? Don’t worry, the watch’s waterproof depth is 100 meters, which has a good waterproof function.(The ordinary Automatic movement is just daily waterproof, need to purchase additional waterproof service which is up to 100 meters.)
Hands Design: Mercedes-logo, Sword, and Breguet-style Shape. After the hands of Rolex watches are treated with tritium, they can glow at night.
