The Rolex Yacht-Master is a sports watch made by Rolex, first introduced in 1992 with the model 16628 in 18-carat yellow gold. In 1994, Rolex released a lady's model (69628) and a mid-size man's model (68628), which was the first time Rolex had ever released a smaller professional size watch. In 1996, Rolex introduced two-tone (stainless steel and 18-carat yellow gold) to the lady's and mid-size lines.
The exquisite Yacht-Master in Rolesium was released in 1997. The term was patented by Rolex in 1932 which gives the Yacht-Master a stainless steel and platinum construction; the bezel and dial are platinum, while the case, band, crown, etc. are stainless steel. This model is also known as the Platinum Yacht-Master.
In 1999, Rolex discontinued the two-tone model 68623, replacing it with the two-tone model 168623 in 2000. The difference between the two models is in the upgraded movement in the 168623, and the heavier 18-carat gold links (the links in the 68623 are hollow).
Then the year 2007 marked another great model release by the brand, the Rolex Yacht-Master II regatta chronograph watch, the world's first watch equipped with a programmable countdown from 1 to 10 minutes with a mechanical memory.
The Everose Yacht-Master, the very first Rolex watch to come with a rubber strap, called the Oysterflex was launched on the market in 2015. The Everose Yacht-Master comes in two sizes - 37mm (268655) and 40mm (126655).
In 2019, Rolex introduced the Rolex Yacht-Master 42, the first time-and-date Yacht-Master watch with a case size of 42 mm. The case, bezel, and Oysterlock clasp are made of white gold, while the bezel has a matte black Cerachrom insert.
The Rolex Yacht-Master is now offered in 37 mm, 40 mm and 42 mm case sizes, starting in 2020. All Rolex Yacht-master models have a water resistance rating of 100 meters [330 ft].
