Rolex Datejust 31 stainless steel yellow gold - performance and prestige
Like all Rolex wristwatches, the Datejust 31 is made with the greatest attention to detail and from the finest materials. To ensure that every component of the luxury watch meets the highest requirements, it is designed, developed and manufactured by Rolex itself. The predecessor of the Datejust 31, the Rolex Oyster Perpetual Datejust, is a milestone in the history of watches and watchmaking. It was presented on the occasion of the company's 40th anniversary in 1945. The Datejust Chronometer from Rolex was the first waterproof wristwatch for men to feature an automatically changing date display that was visible on the dial. Voted the wristwatch of the 20th century in the USA, the Rolex Datejust remains a classic and a certified Swiss chronometer to this day. Only watches that have been thoroughly tested by the Swiss testing institute Contrôle Officiel Suisse des Chronomètres (COSC) can be called chronometers.
