Designed for professional skippers and yachting enthusiasts, the Rolex Oyster Perpetual Yacht-Master II is introduced at this year’s Baselworld in a case constructed from 940L steel, fitted with a Cerachrom bezel insert in blue ceramic. The signature feature of the regatta chronograph, originally released in 2007, is a countdown function which can be programmed from 1 to 10 minutes, using mechanical memory which allows it to be reset to the same countdown duration. It’s accessed through the rotating ring command bezel and can be synchronized on the fly. The movement is calibre 4161, Rolex’s self-winding mechanical chronograph delivering unparalleled precision and reliability, housed in a middle case crafted from a solid block of corrosion-resistant 904L steel. A solid-link Oyster bracelet in 904L steel fitted with an Oysterlock safety clasp finishes the look.
