THE ESSENCE OF THE OYSTER
Watches in the Oyster Perpetual range are direct descendants of the original Oyster, the first waterproof wristwatch by Rolex, on which the brand has built its reputation since 1926. These timepieces benefit from all the fundamental features of the Oyster Perpetual collection – chronometric precision, a waterproof Oyster case, and self-winding of the movement via a Perpetual rotor. Displaying hours, minutes and seconds, and featuring a sophisticated finish, they represent chronometer wristwatches in their purest form. Timeless in their essence, they are continually reinterpreted and have gradually been endowed with the brand’s technical innovations. The varied and constantly evolving colours and design of the dials ensure the Oyster Perpetual never loses its fresh and contemporary appeal.
SUPERLATIVE CHRONOMETER CERTIFICATION
The Oyster Perpetual 28 and Oyster Perpetual 34 are covered by the Superlative Chronometer certification. This exclusive designation is issued to each watch leaving the Rolex workshops, attesting to its excellent performance on the wrist. This in-house certification is strictly controlled by internationally recognized, independent Swiss entities.
In 2026, the Superlative Chronometer certification has been strengthened with the addition of three new testing criteria: resistance to magnetism, reliability and sustainability. These criteria are implemented throughout the design and manufacturing stages of each timepiece – hundreds of checks and validations directly related to the watch’s performance are carried out during these phases. They supplement the criteria established when the certification was redefined in 2015 governing precision, waterproofness, self-winding and power reserve. That year, Rolex set up an exclusive testing protocol for its finished watches, conducted inside the manufacture on fully automated equipment. The precision requirements are particularly stringent: measured after casing the movement, the watch’s accuracy must be between –2 and +2 seconds per day. The rate deviation tolerated by the brand for the precision of a finished watch is significantly smaller than that accepted for official certification of the movement alone.
The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
