Rolex Yachtmaster 35mm watch, round stainless steel case (35mm diameter, 13mm thickness) with shoulders to protect the 18kt yellow gold screw-down Triplock winding crown, special time-lapse rotatable 18kt yellow gold bezel, adjustable stainless steel and 18kt yellow gold Oysterlock bracelet, white mother of pearl dial with 8 round, 1 triangular and 2 baguette ruby hour markers, date calendar at 3 o'clock, 31 jewel Caliber 2235 self-winding Oyster Perpetual chronometer movement, scratch-resistant sapphire crystal, water-resistant to 100 meters.Introduced in 1992, the Rolex Yachtmaster was the first luxury watch that combined the ruggedness of a sports watch with the elegance of a luxury watch. In 1994, Rolex released a lady's model (29mm diameter) and a midsize model (35mm diameter), which was the first time Rolex had ever issued a smaller size professional watch. All three sizes were only available in steel/platinum at that time. Then in 1996, Rolex introduced two-tone (stainless steel and 18kt yellow gold) to the ladies and midsize line. However, the mens 40mm did not get the two-tone model until 2005, at which point they named the two-tone combination "Rolesor". And in 1997, Rolex released the Yachtmaster in "Rolesium", a term patented by Rolex in 1932 which gives the Yachtmaster a stainless steel and platinum appearance. This model is also known as the Platinum Yachtmaster and when first introduced (and for many years later) sold for a premium on the private market (similar to the stainless steel Daytona) due to its scarcity and high demand. Several celebrities favor the steel/platinum Yachmaster model including "Two and a Half Men" star, Charlie Sheen, and Hulk Hogan.
