This very rare Rolex Day-Date Ref. 1803 is presented as a yellow gold head in all-original configuration and remains in very good overall condition. The case is notably sharp, with thick lugs and well-defined edges throughout, showing honest signs of wear consistent with age. All case engravings and numbers are fully visible and intact, with a 5 million serial dating production to approximately 1977. The watch features an original Rolex factory diamond dial in mint condition. All tritium hour plots remain intact and evenly preserved, perfectly matched with the original tritium hands, and continue to react under UV light as expected. The dial presents exceptionally well and is a standout example for this reference. The movement has been professionally serviced in January 2026 and is running properly. The watch was also pressure tested to 3 ATM (30 meters). It is fitted with a new vintage-style 20/16mm brown alligator leather strap and paired with a Rolex gold-plated pin buckle. This example is further accompanied by original Rolex service papers dated 2003, adding to its provenance and collectibility. **Ref:** 1803 **Size:** 36mm **Year:** 1977 📜 Includes: Custom [travel pouch](https://bogossia.com/products/travel-carrying-case) ($50+ value) 💵 Price: $10,950 + FREE overnight shipping with FedEx fully insured.
