From 300 m (30 bar) the watch is suitable for diving. The metre rating refers to the test pressure of the water-resistance test, not a diving depth.

Description

This Rolex Sea-Dweller has the reference number 126603 and shines with a black dial. The case has a diameter of 43mm and is made of stainless steel and 18 carat yellow gold. Also made of stainless steel and yellow gold is the Oyster strap. The Sea-Dweller is equipped with the caliber 3235 and is a chronometer. It also features center seconds and a screw-down crown, as well as a date display.

Gold is prized for its brilliance and value. Stainless steel is a symbol of strength and reliability. These two best qualities go hand in hand. Rolesor is a distinguishing feature of Rolex models, used since the early 1930s and registered as a trademark in 1933. Today, it is a cornerstone of the Oyster collection.

The watch also features a cyclops magnifier. The cyclops magnifier is one of the most distinctive and recognizable elements of the Rolex brand. Named after the one-eyed giant of Greek mythology, the Cyclops Magnifier magnifies the date window with exceptional legibility. Every component of a Rolex watch tells a story. A story of discovery, research, development and the constant pursuit of perfection.

Equipped with a movement entirely developed and manufactured by Rolex, the new generation caliber 3235 guarantees exceptional performance. It is an independent Swiss chronometer certified by the COSC (Contrôle officiel suisse des chronomètres). In addition, Rolex retests the watch after casing it to ensure that its durability is twice that required for official chronometer certification. The final precision tests on the fully assembled watch are carried out using state-of-the-art procedures and equipment that Rolex has developed specifically for this purpose.
