Charting its course
The Yacht-Master II is designed to meet the needs of professional sailors. This regatta chronograph features the world's first programmable countdown with a mechanical memory. It provides precise synchronization with the crucial starting sequence of a yacht race.
904L Stainless Steel
Rolex uses 904L stainless steel for its steel watch cases. 904L is mainly used in the high technology, aerospace and chemical industries, where maximum resistance to corrosion is essential. A superalloy, 904L is extremely resistant and highly polishable. It maintains its beauty even in the harshest environments.
White Dial
The Yacht-Master II’s red-contoured countdown arrow and the seconds hand are readable at a glance against the dedicated 10‑minute countdown graduation on the dial and the graduations on the bezel.
The Oyster bracelet
The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable. It is equipped with an Oysterlock folding clasp, which prevents accidental opening and the Easylink comfort extension link, also exclusive to Rolex. This ingenious system allows the wearer to increase the bracelet length by approximately 5 mm, providing additional comfort in any circumstance.
4161 Movement
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.
Ring Command Bezel
Rolex achieved perfection when it turned its attention to redefining the purpose and functionality of the bezel. Typically, a bezel operates independently from the internal mechanism; however, the Ring Command bezel in the Yacht-Master II regatta chronograph operates in conjunction with it. As a mechanical component linked to the movement, the bezel literally acts as the key to the programmable countdown, allowing it to be set and synchronised to the sequence of race start times. Complex in design, but simple in use, it is functionally beautiful.
