The Yacht-Master II stands apart in the Rolex catalog as the manufacture's most complex contemporary complication. Introduced in 2007, reference 116680 represents the steel iteration of this regatta timer, a watch conceived specifically for the demands of competitive sailing. The white dial variant, known internally as the "Blue Cerachrom" version for its distinctive bezel, creates exceptional legibility against varied maritime conditions. This 2022 example demonstrates Rolex's commitment to purposeful complications, housing the innovative Ring Command bezel system that mechanically interacts with the movement to program the countdown function—a feature unique in modern watchmaking.

The 44mm Oyster case contains caliber 4161, a self-winding mechanical movement representing one of Rolex's most sophisticated calibers. This movement employs a column wheel and vertical clutch architecture to control the regatta chronograph's programmable countdown, allowing sailors to synchronize with race start sequences that typically range from one to ten minutes. The blue Cerachrom bezel rotates bidirectionally and features raised numerals, functioning as both timer setting interface and countdown indicator through the Ring Command system. The movement delivers 72 hours of power reserve through the Paraflex shock absorbers and Parachrom hairspring, maintaining chronometric precision across the complication's operation. Water resistance to 100 meters ensures reliability in the cockpit environment.

At 44mm, this remains Rolex's largest modern sports watch, yet the proportions suit the technical personality of the piece. The white dial provides optimal contrast for the blue accents and red regatta hand, while the Oyster bracelet's Oysterlock clasp and Easylink extension offer secure wear during active sailing. Full documentation accompanies this complete set, though prospective collectors should note the case has received professional touch-up work. The Yacht-Master II appeals to those seeking Rolex's most functionally complex sports watch—a timepiece that operates at the intersection of mechanical ingenuity and competitive maritime pursuit.
