Fans of the Rolex Yacht-Master will remember that Baselworld 2012 saw the debut of a new version of the Replica Rolex Yacht-Master in a Rolesium case. In 2013, that model’s larger successor, the Rolex Yacht-Master II, was the focus, with Rolex introducing the first version of the popular regatta-countdown chronograph watch in a 904L stainless steel case with a blue Cerachrom bezel insert.
The signature feature of the 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 Replica Rolex Yacht-Master’s Oyster case is 44 mm in diameter (as compared to 40 mm for the original Rolex 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 of this Rolex Yacht-Master 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.

The Rolex Yacht-Master II contains Rolex’s automatic Caliber 4161, a column-wheel chronograph movement that has been certified as a chronometer by the Swiss testing agency COSC. The oscillator at the heart of the watch has boasts another Rolex-exclusive development, a blue hairspring made of Parachrom, an patented alloy that Rolex replica watches claims makes the hairspring more resistant to magnetic fields, more stable when exposed to temperature variations, and more capable than a traditional hairspring of maintaining the watch’s timekeeping precision in case of shocks.
The solid-link, steel Oyster bracelet is fitted with Rolex’s hallmark Oysterlock safety clasp, which prevents accidental opening, and features the Rolex-patented Easylink comfort-extension system that allows the wearer to easily increase the bracelet’s length by about five millimeters.
