Date 1505— lug 19mm

The Rolex Date 1505 has a lug width of 19mm. This is a non-standard measurement compared to the more common 20mm, so it is essential to verify this dimension carefully before purchasing a replacement strap. The correct measurement is taken with a digital calliper positioned between the two lugs at the point where they meet the case.

For the Rolex Date 1505, the most suitable materials are vegetable-tanned alligator — for formal settings — and smooth calf leather for everyday wear. Shell cordovan offers a refined alternative with a dense, almost mirror-like texture. It is advisable to select straps with a straight end to ensure a clean fit at the case lugs.

To replace the strap on a Rolex Date 1505, a spring bar tool is required to remove the spring bars securing the strap to the case lugs. Care must be taken to avoid scratching the gold case. On vintage specimens where the lugs may show signs of wear, it is advisable to have the operation carried out by a watchmaker or specialist retailer.

Yes, there are numerous aftermarket straps compatible with the Rolex Date 1505, provided they feature the correct 19mm lug width and a straight end. Milano Straps produces bespoke handcrafted leather straps for this reference, available in various materials (alligator, calf, shell cordovan) with either a buckle or deployant clasp. Compatibility is ensured by the correct width and end geometry.

The lifespan of a leather strap depends on the material, frequency of use, and maintenance. A quality alligator strap, treated with appropriate products and rotated with other straps, can last between 3 and 5 years while retaining good structural integrity. Calf leather tends to develop patina earlier, with an average lifespan of 2 to 3 years. Shell cordovan is notably more resistant to wear and can exceed 5 years with proper care.
