Strap for Lady-Datejust 26 Rhodium Jubilee

The Rolex Lady-Datejust 179160-0036 features a 26mm case with a lug width of 13mm. This measurement should be taken with a vernier calliper between the two lugs, flush against the case, to obtain the net internal width without including the lug overhang.

For the 26mm stainless steel case of the 179160-0036, a belly alligator strap is the classic choice for formal occasions, owing to its symmetrical grain and lustrous texture. Vegetable-tanned calf leather offers the most versatile option for daily wear, while shell cordovan provides the greatest resistance to deformation at a 13mm width.

To replace the strap on the Lady-Datejust 179160-0036, use a spring bar tool or push-pin tool suitable for standard 13mm spring bars. Compress the spring bar, slide it free from the lug, and fit the new strap. It is advisable to work on a soft surface to avoid scratching the stainless steel case.

Yes. Aftermarket straps with a 13mm attachment are compatible with the Rolex Lady-Datejust 179160-0036, provided the end piece is crafted with sufficient precision and the spring bars are of the correct diameter. Milanostraps.it offers a curated selection of handcrafted 13mm straps, with a bespoke option available through Casati Milano.

The lifespan of a leather strap depends on the material and conditions of use. A quality alligator strap, worn daily and maintained correctly — avoiding prolonged water exposure and conditioning every 3–4 months — typically lasts 3–5 years. Vegetable-tanned calf develops a characteristic patina over a similar period, while shell cordovan, owing to its dense fibre structure, generally offers greater longevity.
