Rolex‘s revolutionary regatta chronograph, launched in 2007, is now available for the first time in 904L steel, fitted with a Cerachrom bezel insert in blue ceramic. On the inside of the 44mm Oyster case, the Yacht-Master II features an exclusive function developed by Rolex – a countdown which can be programmed from 1 to 10 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 Yacht-Master II is equipped with calibre 4161, a self-winding mechanical regatta chronograph movement entirely developed and manufactured by Rolex.
