Strap for Lady-Datejust 28 Yellow Gold Fluted / President / Champagne Diamond

The Rolex Lady-Datejust 279178-0017 has a lug width of 14mm. This measurement is specific to the 28mm Lady-Datejust models and is not interchangeable with the 31mm or 36mm versions of the same family. To verify, measure the internal gap between the two lower lugs using a calliper.

For the 18-carat yellow gold case of the 279178-0017, a vegetable-tanned alligator strap with symmetrical belly grain is the most aesthetically coherent choice. Box-calf leather is recommended for everyday wear, whilst shell cordovan develops a distinctive patina over time. A yellow gold deployant clasp or buckle completes the metallic consistency of the combination.

To replace the strap on the Lady-Datejust 279178-0017, use a spring bar tool specifically suited to 14mm lugs. The spring bars are cylindrical with an internal spring mechanism. It is advisable to rest the watch on a protective cushion and work carefully to avoid scratching the yellow gold case. Alternatively, the operation can be carried out at the Casati Milano atelier during the fitting of a bespoke strap.

Yes. The 14mm lug width of the Lady-Datejust 279178-0017 is served by artisan aftermarket straps in alligator, calf leather, shell cordovan and rubber. Milano Straps pieces are crafted with lugs shaped to the contours of the 28mm Oyster case, ensuring a precise fit with no mechanical play or friction on the gold surfaces.

The lifespan of a leather strap for the 279178-0017 depends on the material and frequency of use. A quality vegetable-tanned alligator strap, with appropriate care, retains its structural and aesthetic integrity for 3 to 5 years of regular wear. Calf leather has a similar lifespan but is more susceptible to moisture. Shell cordovan develops a refined patina over time and tends to last longer due to the density of its fibres. All Casati Milano straps carry an 18-month warranty against manufacturing defects.
