      Blue dial


      The colours created for the Oyster Perpetual range start life as a lacquer, which must be meticulously applied in a controlled-atmosphere environment to avoid dust and other contamination. The brass plate of the dial base receives layer upon layer of lacquer, six in all, to form a regular, uniform surface. The last step is varnishing and polishing to bring out the full brilliance and depth of colour. The various inscriptions are then pad printed, and the hour markers and crown riveted by hand. The dial, gleaming in its perfection, is all set to take its place on top of the movement at the watch assembly phase.


      Oystersteel


      Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.


      The Oyster bracelet


      The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection. For the Oyster Perpetual models the Oyster bracelet is fitted with an Oysterclasp.

      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.

      Kooheji Store is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
