Strap for Lady-Datejust 26 Rolesor Diamond Mother-of-Pearl Diamond Jubilee

The Rolex Lady-Datejust 179383-0006 features a 13mm lug width. This is a specific measurement for the 26mm Rolesor configuration and is not a standard width in mass-market production. It is therefore essential to select straps manufactured natively to this size in order to ensure a precise fit with no lateral play at the lugs.

Given the mother-of-pearl dial and the yellow gold/stainless steel Rolesor case of the 179383-0006, a vegetable-tanned alligator strap in bordeaux, cognac or midnight blue offers the finest balance between elegance and material coherence. Box calf leather suits those who prefer smooth surfaces with a long-developing patina. For informal or sporty contexts, anatomical vulcanised rubber is the most practical solution without compromising the Oyster water resistance.

Changing the strap on the Lady-Datejust 179383-0006 requires a fine-tipped springbar tool to remove the spring bars securing the strap to the lugs. The operation should be carried out carefully to avoid scratching the Rolesor case: protecting the lugs with PTFE tape or using a cushion holder is strongly recommended. If in doubt, Casati Milano can perform the fitting in-atelier by appointment.

Yes. Aftermarket straps compatible with the Lady-Datejust 179383-0006 must respect the native 13mm lug width. milanostraps.it offers a curated selection of handcrafted straps produced to this exact size in various materials and finishes. It is important to verify that the fitted strap does not exert lateral pressure on the lugs, which would indicate an incorrect size.

The lifespan of a leather strap depends on the material, tanning method and frequency of use. A vegetable-tanned alligator strap, maintained with a neutral leather conditioner every 2–3 months, typically lasts 3–5 years with daily wear. Box calf leather performs similarly but develops a patina more quickly. Prolonged exposure to water, perspiration and UV radiation accelerates deterioration: for intensive use, it is advisable to alternate the leather strap with a rubber or NATO option.
