The Yacht-Master II carries the same sporty elegance and symbol of distinction as the original Yacht-Master, but with even more robustness in features and capabilities. Created in 2007, the Yacht-Master II is a professional regatta chronograph that provides high-precision timing functions for use during boat races, earning it the title of “The Skipper’s Watch.” It comes in a case size of 44 mm, the largest case diameter made by Rolex.
