Strap for Lady-Datejust 28 Stainless Steel Domed / Oyster / White Roman

The Rolex Lady-Datejust 279160-0016 has a lug width of 14mm. This measurement refers to the internal distance between the two lugs of the case — i.e., the strap width at the attachment point. It is a specific dimension found in high-end ladies' watchmaking and requires dedicated straps with a 14mm attachment.

For the Lady-Datejust 279160-0016 with an Oystersteel case, alligator leather or vegetable-tanned calf straps offer the finest aesthetic balance. The regular grain of alligator complements the clean geometry of the case, while calf leather develops a personal patina over time. For sportier use, nylon NATO or technical rubber straps are functional alternatives consistent with the Oyster water-resistance specification.

To replace the strap on the Lady-Datejust 279160-0016, a double-ended spring bar tool is required. By inserting the tool into the spring bar slot between the lug and the strap, the spring bar is compressed and the strap is released. Care must be taken to avoid scratching the Oystersteel case. It is advisable to entrust the operation to a watchmaker or authorised retailer for first-time replacements.

Yes. Several artisan manufacturers produce aftermarket straps with a 14mm attachment compatible with the Lady-Datejust 279160-0016. Milano Straps and the Casati Milano atelier craft bespoke or ready-to-wear straps in alligator, calf, shell cordovan and other materials, with a stainless steel buckle or deployant clasp, fully respecting the geometric specifications of the original Rolex lugs.

The lifespan of a leather strap on the Lady-Datejust 279160-0016 depends on the quality of the tanning and daily use. A high-quality alligator or vegetable-tanned calf strap can last between two and five years with regular wear, provided it is kept away from prolonged exposure to water, perspiration and direct sunlight. Rotating between two or more straps significantly extends the life of each one.
