The Sea-Dweller, an expert instrument watch for deep-sea diving from the Rolex stable, turns 50 this year and to mark this event the big crown has introduced an all-new version, using a larger case and modern quality, in Baselworld 2017.
The first Rolex Sea-Dweller, created in 1967, was created out of Rolex’s relationship with Comex, a professional French diving firm. The initial models of this first ever reference (Ref. 1665) was designed in the Submariner and was nearly exclusively supplied only to sailors.
One of its many notable features was a helium escape valve, patented by Rolex watches that same calendar year, which maintained the watch water-resistance while regulating the air pressure accumulated in its case through the decompression stages of deep-water saturation dives.
The brand new Sea-Dweller utilizes a 43 mm instance, 3 mm over the outgoing version. From the Rolex dip watch catalogue now, the Submariner includes a 40 mm case, the Sea-Dweller gets a 43 and the Deep Sea understands a 45 mm case. For the first time, the model also gets a Cyclops lens over the date window at 3 for improved legibility.
In a move that will leave collectors joyful, the text”Sea-Dweller” appears on the dial in red, just like in the first from 1967. Some versions of this Ref. 1665 carried two red text traces on the watch dial (Sea-Dweller in the first and Submariner 2000 in the next ) and came to be referred to as the Double Red Sea-Dweller. The Dual Reds and Comex dial Sea-Dwellers are highly collectible vintage Rolex watches today.
The case of this 50th anniversary variant utilizes Rolex’s iconic Oyster construction.
The screw-down crown, protected by a crown guard integrated into the case centre, uses Rolex’s Triplock triple waterproofness system, which ensures protected waterproofness for your watch’s interior in precisely the exact same fashion for a submarine’s hatch.
While the first was depth-rated to 2,000 meters, the new Sea-Dweller is water-resistant to a depth of 1,220 meters (4,000 feet). It features a 60-minute graduated, unidirectional, rotating sailors’ bezel fitted with a patented black Cerachrom bezel insert. The black dial has large hour markers Full of Chromalight, a Rolex-developed luminescent substance that emits a long-lasting blue glow in low-light conditions
The opinion comes with the newest Rolex Caliber 3235, a self-winding motion that boasts 14 patents. This represents the first time Rolex has used this recently introduced, technically exceptional movement in one of its”Professional tier” timepiece.
Like all new Rolex watches, this Sea-Dweller carries the Superlative Chronometer certification, instituted by Rolex in 2015, which ensures a high level of precision and timekeeping performance (-2/+2 minutes daily ).
A 4 Hz motion, it uses Rolex’s patented blue Parachrom hairspring, which Rolex says is up to 10 times more precise than a conventional hairspring when exposed to burnout, also has a power reserve of 70 hours. The bracelet also includes a double-extension system which permits adjustments to be made without the use of tools, allowing the eye to be worn over a diving suit around 7 mm thick.
Rolex’s Fliplock extension link extends the bracelet by 26 mm, while its Glidelock system allows fine adjustment of the bracelet span at 2-mm increments, for a total of approximately 20 mm.
