Strap for Lady-Datejust 26 Silver Oyster

The Rolex Lady-Datejust 179160-0023 has a lug width of 13mm. This measurement is taken with a digital calliper positioned between the two lugs, flush against the case. It is a dimension specific to the 26mm Lady-Datejust and requires aftermarket straps manufactured to this exact width, with shaped ends to fit correctly against the curved Rolex lugs.

For the stainless steel Lady-Datejust 179160-0023, the most suitable materials are vegetable-tanned alligator — for a formal register with natural grain — and box-calf leather for everyday versatility. Shell cordovan is ideal for those seeking long-term resilience and natural lustre. A 13mm steel buckle or deployant clasp completes the pairing in harmony with the watch's metallic components.

To replace the strap on the Lady-Datejust 179160-0023, a fine-tipped watchmaker's springbar tool is required. The 26mm Rolex lugs accommodate spring bars of reduced diameter: it is advisable to work on a soft cushion to protect the case. Compress the ends of the spring bar and slide the strap out laterally. Care must be taken to avoid scratching the satin-finished case surfaces. If in doubt, the operation should be entrusted to a qualified watchmaker.

Yes, aftermarket straps specifically made for the 13mm lug width of the Lady-Datejust 179160-0023 are available. It is important to select straps with curved or straight ends compatible with the Rolex 26mm lug profile, and to verify that the spring bar is the correct length. Milanostraps.it offers a curated selection of 13mm straps in various materials — leather, cordovan, rubber — crafted for this specific model.

The lifespan of a leather strap depends on the material, care routine and frequency of use. A quality alligator strap, properly conditioned with nourishing cream and protected from excessive moisture, typically lasts 2–4 years with daily wear. Box-calf leather develops a personal patina but is more sensitive to water. Shell cordovan, owing to its dense fibrous structure, tends to last considerably longer with minimal maintenance.
