All About Rolex Yacht-Master
The design is more luxurious compared to a Rolex Submariner since it is mainly used for outdoor and sea-surface activities but it can also be worn underwater at a maximum of 320 feet. Later on, they started producing different sizes for this model type - the Rolex Yacht-Master 37 mm, Rolex Yacht-Master 40 mm, and Rolex Yacht-Master 42 mm in diameter. The change of size from the bezel is to improve the contrast of the sand-blasted background and the legibility of numbers. Also, one of the features of this watch is that it can measure the sailing time from anchor float to another.
