A Rare Sigma Dial in Striking Blue
Since its debut in 1945, the Rolex Datejust has remained a timeless symbol of balance between elegance and reliability. By the late 1970s, the Datejust had evolved into a model of refined vintage appeal—versatile, robust, and effortlessly stylish. The reference 1603, with its engine-turned bezel and classic Jubilee bracelet, remains one of the most recognisable and respected vintage Rolex watches ever produced.
This particular example from 1978 is made all the more desirable by its original and exceptionally rare blue pie-pan Sigma dial—an uncommon and highly collectable feature that sets it apart from the majority of its contemporaries.

• Recently serviced in 2025 and running perfectly on time
• Fitted with a brand new plexiglass crystal

With its rare dial, enduring proportions and Rolex DNA, this piece captures everything that makes the Datejust one of the most influential watches ever created.
