Rolex New Oyster Perpetual Yacht-Master II EVEROSE ROLESOR

Rolex Oyster Perpetual Yacht-Master II embodies all of the intense emotion a regatta arouses. By its impressive size, evocative power and sleek design, this unique regatta chronograph echoes directly the Maxi Yachts built to brave the oceans. The new version is the first Professional watch in the Oyster collection to be available in EVEROSE ROLESOR – an exclusive combination of the 904L steel superalloy and 18 ct EVEROSE gold.

Equipped with a programmable countdown with a mechanical memory, the Oyster Perpetual Yacht-Master II is an innovative and pioneering watchmaking complication, based on interaction between the movement and the bezel. It allows the skipper to programme a regatta countdown sequence from 1 to 10 minutes. Once the countdown has been launched, the skipper can, if necessary, synchronize his chronograph to the official race countdown. Thanks to the Yacht-Master II, experienced sailors and yachting enthusiasts have at their disposal an efficient tool to assist in crossing the starting line at the very moment the horn sounds.

With its numerous innovative watchmaking features, the Yacht-Master II model, launched in 2007, is the epitome of the brand’s creative force and technology. Its functions depend on a major innovation: the exclusive RING COMMAND bezel designed and developed by Rolex. Rotatable through 90° and interacting with the movement, it serves to initialize and then lock the countdown programming.

The model’s 4160 movement, entirely designed and developed by Rolex, is fitted with a PARACHROM hairspring, 10 times more resistant to shocks and insensitive to magnetic fields. The countdown is operated by a column wheel and a vertical clutch. A number of micro-components in this unique movement are produced by UV-LiGA – a new technology, entirely mastered in-house by Rolex, which enables the production of components whose fineness or geometry makes them impossible to manufacture by traditional means.

The Yacht-Master II’s case, stamped from a block of 904L steel extremely resistant to corrosion, offers all the qualities of waterproofness that have made the reputation of Oyster watches. Not least thanks to its TRIPLOCK winding crown that screws down tightly against the case like the hatch of a submarine. The pink gold of the bezel and the bracelet’s centre links is 18 ct EVEROSE gold, an exclusive alloy developed by Rolex and manufactured in its own foundry. The blue CERACHROM bezel insert, virtually impervious to scratches, corrosion-resistant and non fading, is also patented and manufactured by Rolex.
The excellent legibility of the Yacht-Master II’s dial demonstrates the constant attention to functionality in the Oyster Professional collection. The red countdown minute and seconds hands are readable at a glance against the graduations on the dial or bezel. The bracelet, in 904L steel and 18 ct EVEROSE, is fitted with an EASYLINK 5 mm comfort extension link and an OYSTERLOCK clasp with a safety catch, two further Rolex innovations.
