Subtle but significant redesign is the hallmark of the recently redesigned Rolex Oyster Perpetual Submariner. The watch retains the Submariner’s immediately recognizable look but dispenses with the date window of previous models and incorporates several new technical innovations exclusive to Rolex.
The watch’s unidirectional-rotating 60-minute graduated bezel is now enhanced with a black insert made of virtually scratchproof, non-fading, corrosion-resistant ceramic that Rolex calls Cerachrom. The graduations are coated in a PVD process with a thin layer of platinum. The hour markers and hands on the sleek, black dial are filled with Rolex’s proprietary Chromalight luminescent material, which emits a blue glow that the company claims lasts twice as long as that of other luminous substances used on watch dials. The classical Oyster case of the new Submariner is 40 mm in diameter and water-resistant to a depth of 300 meters (1,000 feet). The case middle is crafted from a solid block of particularly corrosion-resistant 904L stainless steel, and the fluted caseback is hermetically screwed down with a special tool exclusive to Rolex watchmakers. The winding crown, fitted with Rolex’s patented Triplock system, screws down securely against the case in a manner akin to a submarine’s hatch and is protected by a crown guard. The crystal is made of scratch-resistant synthetic sapphire. (Click on the watch photos to enlarge the images.)
The high-precision movement inside the highly water-resistant case, automatic Caliber 3130, is a COSC-certified chronometer entirely developed and manufactured by Rolex. The movement’s oscillator has a hairspring made of blue Parachrom, a Rolex-patented alloy that is unaffected by magnetic fields and maintains stability and precision when exposed to temperature variations and shocks. The new Oyster Perpetual Submariner is fitted with a solid-link Oyster bracelet in 904L steel. The bracelet includes a new-generation Oysterlock safety clasp and Glidelock extension system, located beneath the clasp cover, which allows fine adjustments of the bracelet length in 2-mm increments, for a total of approximately 20 mm, without using any tools. This feature allows the watch to be worn over a diving suit up to 3 mm thick, and also provides additional comfort on the wrist.
This newest generation of Rolex’s famous divers’ watch retails for $7,500.
