Rolex Day-Date 36 | 18K Yellow Gold | Green Leather Strap | Ref. 1803

The Rolex Day-Date Ref. 1803 is one of the most iconic vintage Rolex references, known for its classic 36mm Oyster case, fluted bezel, acrylic crystal, and signature day and date display. This example carries a 5.50M serial, dating it to approximately 1978, placing it toward the later production period of the vintage 1803 generation.

This watch is fitted on a green leather strap, giving the Day-Date a more unique and relaxed wrist presence compared to the traditional President bracelet configuration. The combination of the classic Day-Date case profile, vintage acrylic crystal, and green leather strap gives this example a distinct vintage personality while still keeping the elegance that made the Day-Date one of Rolex’s most recognizable models.
