The Yacht-Master II, a Professional regatta chronograph created in 2007, features an exclusive function developed by Rolex: a programmable countdown with a mechanical memory, which can be synchronized on the fly. A function that 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 programming is accessed, and locked, via the rotatable Ring Command bezel, an innovative interface between bezel and movement developed by #Rolex.
