Reference 1603 is a vintage Datejust designation — pre-sapphire crystal, pre-quickset date, produced in an era when Rolex used 14k gold in their two-tone pieces rather than the 18k that became standard later. The serial number in the 2 million range places this in the late 1960s to early 1970s production — a vintage window with strong collector interest. Black dial with diamond markers in the Jubilee oval link bracelet creates a dressy combination. Acrylic crystal gives it the gently convex profile of its era. The 36mm case dimensions are considered ideal for both men’s and women’s wrists.
Vintage reference 1603 Datejust collectors in Houston’s Tanglewood and Memorial neighborhoods and nationally understand the nuances of the 14k versus 18k discussion and the specific dial variations across the reference. Houston Gold Exchange sources vintage Rolex with attention to these details because our vintage watch buyers require accurate, specific description rather than generic estate descriptions.
