Bidirectional Rotatable Bezel
The Yacht-Master’s bidirectional rotatable 60-minute graduated bezel is made of precious materials. The raised polished numerals and graduations stand out clearly against a matt, sand-blasted background.

Chocolate Dial
Like all Rolex Professional watches, the Yacht-Master 40 offers exceptional legibility in all circumstances, and especially in the dark, thanks to its Chromalight display. The broad hands and hour markers in simple shapes – triangles, circles, rectangles – are filled with a luminescent material emitting a long-lasting glow.

Everose Rolesor
Gold is coveted for its lustre and nobility. Steel reinforces strength and reliability. Together, they harmoniously combine the best of their properties. A true Rolex signature, Rolesor has featured on Rolex models since the early 1930s, and was trademarked as a name in 1933. It is one of the prominent pillars of the Oyster collection.

MODEL AVAILABILITY
All Rolex watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict Rolex production capacity and, at times, the demand for Rolex watches outpaces this capacity.
Therefore, the availability of certain models may be limited. New Rolex watches are exclusively sold by Official Rolex Retailers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
Srichai Watch is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
The Rolex Yacht-Master and Yacht-Master II embody the spirit of the sailor. Inspired by the rich heritage that has bound Rolex to the world of sailing since the 1950s, the Yacht-Master blends function and style, while the Yacht-Master II brings together the finest in Rolex technology to create a regatta chronograph built for yachting competition.
