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.
The Yacht-Master II was first introduced in 2007 in white gold and yellow gold. In 2011 a version in stainless steel / Everose was added to the collection, while the stainless steel version was added to the collection in 2013 and in the same year the caliber 4160 movement was updated to the 4161.
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. Just like the Sky-Dweller, the Yacht-Master 2 features a 'Ring Command' bezel that operates in conjunction with the movement, acting as the key to the programmable countdown.
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.
