Strap for Lady-Datejust 28 Everose Diamond / President / White Roman

The Rolex Lady-Datejust 279135rbr-0023 features a lug width of 14mm, measured internally between the two lugs at the strap attachment point. This dimension is specific to the 28mm case and requires straps manufactured to this precise tolerance to ensure a correct fit without lateral play.

The most coherent material choice for the jewellery-grade aesthetic of the Lady-Datejust 279135rbr-0023 is alligator leather in vegetable tannage, preferably in bordeaux, cognac or midnight blue. The square-scaled grain complements the diamond-set bezel and Everose gold case. For everyday wear, smooth Tuscan calfskin or vulcanised rubber are sound alternatives that preserve the technical specifications of the calibre 2236.

Strap replacement requires a dedicated spring bar tool with a fine-tipped lever. The lugs of the 28mm Lady-Datejust are narrow and demand a reduced-diameter tool to avoid scratching the Everose gold case. It is advisable to work on a soft cloth surface and, if in doubt, to entrust the operation to a watchmaker or to the Casati Milano atelier.

Yes. Any strap with a 14mm lug width is technically compatible, provided the spring bars are of the correct diameter and the leather or synthetic material meets the standard expected for a timepiece of this calibre. Milanostraps.it offers a curated selection of handcrafted 14mm straps, with bespoke production available through the Casati Milano atelier.

Longevity depends on the material, frequency of use and exposure to perspiration and environmental conditions. A high-quality vegetable-tanned alligator strap, worn regularly but not continuously, will maintain structural integrity and aesthetic quality for 3 to 5 years. Calfskin straps typically last between 2 and 4 years. The 18-month production defect warranty offered by Casati Milano covers any stitching or attachment failures not attributable to normal wear.
