Strap for Rolex Lady-Datejust 179163

The Rolex Lady-Datejust 179163 has a lug width of 13mm. This measurement should be taken with a digital calliper positioned inside the lugs, in contact with the walls where the spring bar is inserted. This is a specific dimension: straps measuring 12mm or 14mm will not align correctly with the case.

For a two-tone Rolesor case in steel and 18-carat yellow gold, an alligator strap with vegetable tanning and a bombed grain is the most aesthetically coherent choice: the patina it develops over time complements the gold's lustre without overpowering it. For intensive daily wear, vulcanised rubber with a stepped profile is the most practical solution. In both cases, the lug width to observe is 13mm.

To replace the strap, the spring bars connecting the bracelet or strap to the case lugs must be removed. A thin-tipped spring bar tool of 0.8–1mm should be inserted into the hole on the side of the lug. The spring bars on the Lady-Datejust are approximately 13mm in length and 1.5mm in diameter. It is advisable to work on a soft surface to avoid scratching the case.

Yes. Aftermarket straps compatible with the Rolex Lady-Datejust 179163 must have a lug width of 13mm and respect the curvature of the end piece in contact with the lugs of the 26mm Oyster case. Milanostraps.it offers handcrafted 13mm straps in alligator, calfskin and rubber, made to order at the Casati Milano atelier or available online as ready-to-ship models.

The lifespan of a leather strap depends primarily on the material, tanning method and pattern of use. A vegetable-tanned alligator strap, maintained periodically with a neutral leather cream, will retain its structural and aesthetic integrity for 3–7 years with daily wear. Smooth calfskin typically lasts 2–4 years under comparable conditions. Prolonged exposure to perspiration, perfume and water accelerates deterioration: it is advisable to rotate between two or more straps for a Lady-Datejust.
