The Rolex Yacht-Master II — the successor to the original Rolex Yacht-Master — debuted in 2007 and introduced a Rolex-exclusive regatta countdown function that 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 start-time countdown. Programming the countdown is easy, by means of the rotatable Ring Command bezel, a Rolex-developed system linking the bezel to the movement.

The Rolex Yacht-Master II has a 44-mm Rolex Oyster case (available in several precious metals, in Rolex’s proprietary “Rolesium” material, or in a new stainless steel version with blue Cerachrom bezel, shown below.) The watch contains the Rolex manufacture Caliber 4161, which has a COSC chronometer certification and includes a column-wheel chronograph.
