An obession with perfection
A high-performance timekeeping instrument, designed for professional skippers as well as yachting enthusiasts, the new Yacht-Master II is a pure example of Rolex expertise in terms of precision, functions and reliability.
Programmable countdown and ring command bezel
The Yacht-Master II features an exclusive function developed by Rolex: a countdown which can be programmed from 1 to10 minutes and incorporates a mechanical memory, allowing it to be reset to the same countdown duration. Once launched, it can also be synchronized on the fly, enabling it to be adjusted to match the official regatta countdown. The countdown function responds ideally to the need for precise timing during the crucial starting sequence of a regatta. Although technically complex, it is essentially very simple to use: the countdown is programmed via the rotatable Ring Command bezel, an innovative interface between bezel and movement developed by Rolex.
The Oyster Case
Symbol of waterproofness and robustness
The Oyster case is one of the foundations of the reputation for excellence of Rolex watches. Invented by Rolex in 1926, it was the world’s first waterproof case for a wristwatch thanks to its patented system of screwing down the bezel, case back and winding crown against the middle case. Like the mollusc, the Rolex Oyster is robust and clamped shut. It provides a hermetic environment that protects the high-precision Perpetual movement from water, dust, or pressure.
Regatta chronograph and superlative chronometer
The Yacht-Master II is equipped with calibre 4161, a self-winding mechanical regatta chronograph movement entirely developed and manufactured by Rolex. The result of over 35,000 hours of development, the Yacht-Master II introduces a new regatta countdown with a unique, patented mechanical memory created by Rolex. A number of the 360 components in the 4161 movement are so tiny or complex that they can only be made by new, cutting-edge technology.
Like all Rolex Perpetual movements, the 4161 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
Certified Swiss Chronometer
The four simple words Superlative Chronometer Officially Certified on a Rolex watch dial mean that the very movement inside the timepiece has endured 15 days and nights of testing by COSC (Contrôle Officiel Suisse des Chronomètres – Swiss Official Chronometer Testing Institute), an independent not-for-profit association. To receive COSC certification as a Swiss chronometer, a watch must demonstrate extreme precision in a variety of positions and temperatures. Rolex is unique in the industry: this is the standard level of quality required of every Rolex wristwatch movement.
