Several decades later, the standard diameter of luxury sporty copy Rolex watch has achieved to 40 mm which is a suitable size for majority of men. Submariner, GMT-Master, Yacht-Master and the former Sea-Dweller are all designed with such a suitable size. However, Rolex creates the obvious different between Submariner and Sea-Dweller. So the diameter of Sea-Dweller increases to 43 mm.

In addition to the large diameter, the entire watch has been enlarged including the bracelet, bezel, hour markers, hands and buckle. The diameters of Rolex diving watches are different. Submariner is 40 mm, Sea-Dweller is 43mm while Deepsea is 44mm. As the professional diving watch, the Rolex Sea-Dweller fake watch with black ceramic bezel has been equipped with the helium escape valve, which is water resistant to a depth of 1220 meters.

The case of the knockoff watch with Oystersteel case has been designed again and the lugs become much shorter and more curving, making the timepiece suitable for who have thin wrists.
