Strap for Lady-Datejust 28 Platinum Diamond / President / Pink Roman

The Rolex Lady-Datejust 279136RBR-0012 has a lug width of 14mm. This measurement should be taken with a digital calliper at the lower lug attachment point of the case, and is specific to this 28mm variant of the Lady-Datejust family. It should not be confused with the 26mm or 31mm variants, which feature different lug widths.

For a platinum 950 case with a diamond-set bezel, a square-scale alligator strap is the most coherent choice in terms of construction quality and surface texture. French CITES-certified alligator leather with a regular grain complements the matte finish of the platinum without competing with it. Alternatively, vegetable-tanned calf leather develops a personal patina over time, softening the formal register of the piece. Both options in 14mm are available on milanostraps.it.

The strap is removed using a dedicated spring bar tool or a flat watchmaker's screwdriver, inserted into the slot of the spring bar connecting the strap to the case lugs. It is advisable to rely on a watchmaker or specialist atelier to avoid scratching the platinum case, a material particularly susceptible to contact marks from metal tools. Casati Milano offers this service by appointment.

Yes. All straps with a 14mm end width and standard spring bars are technically compatible with the 279136RBR-0012. milanostraps.it offers a selection of handcrafted 14mm straps in alligator, calf leather and shell cordovan, produced with hand-stitched seams and calf leather linings. Compatibility is determined by the lug width, not by the brand of the original bracelet.

The lifespan of a leather strap depends on the material, frequency of use and care applied. A quality vegetable-tanned alligator strap worn daily typically lasts 2 to 4 years before the leather shows structural wear at the flex points. Milano Straps straps produced by Casati Milano carry an 18-month guarantee against manufacturing defects. Longevity is significantly extended by avoiding prolonged contact with water, perfume and perspiration.
