By TLex A true diving legend gets an upgrade - Rolex have updated their legendary Oyster Perpetual Sea-Dweller 4000 for 2014.
The new 40mm Sea-Dweller combines strands of DNA from original S-D models dating back as far as the 60s and 70s with the latest in dive watch technologies employed by the DEEP SEA, the DEEP SEA Challenge and the latest Submariner models.
The Sea-Dweller has a fascinating history spanning 47 years, when the very first Sea-Dweller was born in 1967 with its 610 meters of water-resistance.
More than a decade later in 1978, the Sea-Dweller, a dive watch specially developed for aquanauts was depth rated to its current water-resistance of 1220 meters (4,000 feet).
But it wasn't water-resistance that defined this watch, it was the tiny valve on the side of its case (still present on the 2014 model) that made the Sea-Dweller the legendary diver that it is and so it remains very much an integral part of the watch's design.
Its 2014 updates include: a Cerachrom bezel insert made from a ceramic that is virtually impervious to scratches and ultraviolet rays. A beautiful blue Chromalight display with long-lasting luminescence. A paramagnetic blue Parachrom hairspring for its 3135 caliber.
An Oysterlock safety clasp; and Rolex Glidelock extension system. A thick Sapphire crystal that rises above the dial in a way that is somewhat reminiscent of the DEEP SEA Challenge watch.
And of course the aforementioned function that made the Sea-Dweller what it is, a Helium Escape Valve devised to expel built up helium in the watch after prolonged periods spent in Helium rich environments.
Another superlative diver design from Rolex - can't fault it! Follow the link HERE to read up on the Sea-Dweller's full history, and HERE to watch the 2014 S-D video.
