The Rolex Sea Dweller and Submariner are perhaps the two most well-known in Rolex’s sports watch lineup. They are beautifuldiver’s watches designed to handle water and can go hundreds of meters down into the water and still work.
First, the similarities. The most observable similarity is their ability to withstand total submersion in deep water for long periods of time without causing any disturbance in functionality or precision. The Rolex Submariner and the Rolex Sea Dweller both feature a scratch resistant synthetic sapphire crystal, a unidirectional bezel that can only be turned counterclockwise, and a new Triplock system that now features a triple gasket function that screws down firmly onto the case tube and against the Oyster case, therefore offering an additional layer of protection while the watch is submerged. Both timepieces also contain a self-winding mechanism with a perpetual motor a case made of either a solid block of 904L (which is corrosion resistant) or gold.
The Rolex Submariner was designed for recreational divers, and has a depth of 1,000 feet. In contrast, the Rolex Sea-Dweller is suited for serious deep sea divers. The Sea Dweller line of watches features options that have depth ratings of 2,000 to 5,000 feet in most instances. In fact, the Sea Dweller line has a new model called the DEEPSEA watch that has a depth rating of 12,800 feet; The Rolex Submariner counts with a Cyclops Lens feature, which magnifies the date display. In contrast, the Rolex Sea-Dweller models have the inclusion of a date window, without the crystal magnifier lens; The Rolex Sea-Dweller wristwatch is bigger and thicker (4mm), than the Saphire Crystal on the Rolex Submariner. In addition, the Rolex Submariner lacks a helium escape valve, a feature that allows the more advanced Sea-Dweller to decompress without damage.
Designed for those who enjoy spending time in the water, the Rolex Submariner and the Rolex Sea Dweller both are two exceptional timepieces that are most suited to aquatic activities. Rolex Submariner Replica is more suitable for those who enjoy diving but don’t go too far down in the water. And the Rolex Sea Dweller is more suited for deep sea divers and treasure hunters.
