The First Rolex Deepsea Precious Metal Watch

As we all know, because high-end diving watches need to withstand super strong water pressure, many parts including the watch mirror and bottom cover often need to be reinforced, making it difficult to achieve thinness and lightness. How to balance performance and user experience has always been a problem that has plagued advanced diving watches. In order to achieve 3900 meters of water resistance, the Rolex Deepsea uses a 44mm case diameter and 17.7mm thickness, which has been controversial for wearing comfort, and this is still for the Oyster steel case; the newly added Deepsea 18K gold model this time, the watch The case and chain are entirely made of 750 gold, once again pushing the weight of the watch to a new high https://www.aomwatches.is/.

Rolex diving watches are divided into series by waterproof level. From low to high, they are Submariner (300 meters), Sea-Dweller (1220 meters), Deepsea (3900 meters), and Deep Sea Challenge (11,000 meters). Before the mass production of the Deep Sea Challenge model in 2022, Deepsea was once the king of Rolex diving watches.

In order to achieve such performance, the Rolex Deepsea uses a technology called "RING LOCK SYSTEM". The words "RING LOCK SYSTEM" are clearly visible on the outer layer of the dial. In short, it consists of three parts: the first is the BioDur 108 alloy ring, which is located inside the case and has a tensile resistance 3 times that of conventional steel; the second is the RLX titanium bottom cover, which is used to absorb pressure deformation. Although the crown, case, and strap of this watch are made of 18K gold, the bottom cover is still made of RLX titanium due to material characteristics; the third one is a reinforced sapphire mirror. The thickness of the watch mirror reaches 5.5mm.

There is a helium escape valve on the side, which is a common practice in many deep diving watches. It can discharge the accumulated helium inside the case during the ascent process to ensure the stability of the watch. In addition to the material difference, the details of the deep dive 18K gold model are also slightly different: the Oyster steel model uses a black Cerachrom ceramic bezel, with a blue upper and lower black gradient dial (D-blue color), and the word "DEEPSEA" on the dial It is light green. The new 18K gold model uses a blue Cerachrom ceramic bezel and a blue dial. “DEEPSEA” in the middle of the disk and “RING LOCK SYSTEM” surrounding the outside are presented in gold.
