Rolex is the world's most recognised watch brand. Founded in 1905, it produces approximately one million watches per year yet remains one of the most difficult brands to access in boutique : steel sport models (Submariner, Daytona, GMT-Master II) consistently trade above their catalogue price on the secondary market. In 2026, a pre-owned Rolex starts from CHF 4,000 for a vintage Datejust, and from CHF 12,000 for current sport references like the Submariner. This guide helps you identify the iconic models, understand prices, and buy safely.
