If you are an avid diver or perhaps a lover of fine luxurious watches, here is everything you need to understand the Rolex Sea-Dweller series.

A Brief History

The Rolex Sea-Dweller 126600 is a watch with a storied story spanning over 50 yrs and is inextricably linked with the history of diving. The original variations of the Sea-Dweller were based for the initial Submariner design, that was created following the dramatic embrace recreational diving after the end of WW2.

The Submariner was created to withstand aquatic environments as much as 330 ft., which was later on expanded to 660 feet. But to meet the needs of professional divers, Rolex worked with Comex, a France deep-sea diving company, to experiment with watches designed for saturation diving. From this research came the particular Sea-Dweller’s hallmark feature, the particular helium escape hatch, which allowed the watch to be worn in under-sea stresses up to three times that of the particular Submariner.

As the Sea-Dweller may not be as well referred to as Submariner series, it has a heritage founded more on practicality rather than big-screen fame. Its high-pressure survivability makes it the go-to choice for divers spending a lengthy period in the ocean’s depths.

The Sea-Dweller’s History

Initially developed in 1967 for the diving industry, the Sea-Dweller came with a date dial to the right quarter for scuba divers to better gauge longer stays underwater and was graded for up to 1, 600 feet. submergence. The Double Reddish Sea-Dweller, produced between 1971 and 1977, featured a reference to the original Submariner to the face to make the Sea-Dweller more appealing to the public, who understood the Submariner from the James Bond movies. However , the Sea-Dweller transformed from the Double Red to the 1665, nicknamed the particular “Great White, ” and yes it took on its own identity.

While the 1665 had been still in production, further improvements were made, including a sapphire crystal and a larger helium escape control device, which meant an improved submergence rating for the watch up to depth of 4, 1000 ft. This new version was known as the 16660 model but was discontinued in 2008 and replaced by the Deepsea Sea-Dweller. A special edition Sea-Dweller, nicknamed the Deepsea Problem, accompanied James Cameron to the bottom of the Mariana Trench , making it through a depth of 35, 788 ft.

Helium Escape Valve

The Sea-Dweller was the first diving watch to be fitted having a helium release valve. Around the same time that the view was being developed, archeological diver T. Walker Lloyd suggested using an one-way valve to solve decompression issues.

The issue with underwater mechanisms is that saturation habitats contain an atmosphere with higher concentrations of helium or even hydrogen. As the smallest gas particles, these gases can diffuse through various closes which block out water. Like a diver decompresses, these gas expand and cause damage to the particular watch’s internal component, such as the crystal quite literally taking off due to the outward pressure.

As an option, the helium escape valve automatically releases pressure once the force is enough to normally overcome the tension of a spring. The spring activates the one-way valve, venting pressure within the watch and preventing damage.

Feature of the Rolex Sea-Dweller 126600

The Rolex Sea-Dweller 126600 has made many improvements over earlier models , both aesthetically and mechanically. The 126600 has had its diameter improved to 43mm, with the remaining watch being increased in dimensions to maintain its stunning amounts. A cyclops lens had been added over the date to ensure enhanced visibility.

Mechanically, the caliber 3135 internals have been upgraded in order to caliber 3235. This upgrade’s most significant improvement is an increased power reserve, from 48 hours up to 70 hours. This upgrade follows nearly 30 years of design using the caliber 3135. Based on how Rolex has been steadily upgrading all of their new releases to quality 3235, it is clear that they will replace caliber 3125 entirely in the future.
