The signature feature of the new Rolex Oyster Perpetual Yacht-Master II, first introduced in 2007, is its regatta countdown function, developed exclusively for Rolex, which can be programmed from 1 to 10 minutes and incorporates a mechanical “memory” that allows it to be reset to the same countdown duration used previously. Once launched, the countdown can also be synchronized on the fly, enabling adjustment to match the official regatta countdown — an important feature because of the need for very precise timing during the crucial starting sequence of a regatta. Programming the countdown is easy, by means of the rotatable Ring Command bezel, a Rolex-developed system linking the bezel to the movement.

The watch’s Oyster case is 44 mm in diameter (as compared to 40 mm for the original Yacht-Master) and water-resistant to 100 meters. The middle case is crafted from a solid block of particularly corrosion-resistant 904L steel. The fluted caseback is hermetically screwed down with a special tool used exclusively by Rolex watchmakers. The screw-down winding crown is fitted with the patented Triplock triple-waterproofing system and is protected by a crown guard integrated into the case middle. The crystal is made of scratch-resistant sapphire. The bidirectional rotating Ring Command bezel adds a splash of nautical blue with its Cerachrom insert, made of extra-hard corrosion-resistant ceramic, with engraved numerals and inscription coated in platinum
