The Rolex Datejust 1603 is a vintage watch model that holds a special place in the history of Rolex timepieces. It was part of the Rolex Oyster Perpetual Datejust series, which was introduced in 1945 to commemorate the brand's 40th anniversary.
 
The Rolex 1603 boasts a timeless and elegant design that has stood the test of time. It features a 36mm stainless steel case, making it robust and durable for everyday wear. The case is paired with a matching stainless steel Jubilee bracelet, known for its five-piece links, providing both comfort and style. The Rolex datejust reference 1603 is powered by the calibre 1570 self winding movement. 
 
This particular model features the rarer grey 'soleil' dial, or as some collectors call it, the 'ghost dial,' due to the white font being less visible under direct light. The case, Jubilee bracelet, and engine-turned bezel are all in excellent condition.
 
As you can see from the images, all the lume plots are intact and have turned slightly creamy over time. 
 
The watch benefits from having a 2023 Rolex service, and comes with a years manufacturers warranty.
