When it comes to Rolex's sports watches, the focus is often on their famed Daytona, GMT-Master, Explorer of Submariner, rather than the Yacht-Master. Even today can the Yacht-Master be considered a new kid on the block, as this model wasn't introduced until 1992 and doesn't have such a long history as the other Rolex sports models mentioned. Some refer to it as the Submariner's casual sibling, and there is some truth to this. While visually, it has some similarities, there are also differences. The 60-minute graduated bezel is bidirectional, and Yacht-Master is 'only' waterproof to 100 meters. In effect, this makes it the perfect watch for people who enjoy all kinds of water sports but don't scuba dive.
