Strap for Lady-Datejust 28 Rose Gold / Diamond / Rose / Jubilee

The Rolex Lady-Datejust 279135RBR-0026 has a lug width of 14 mm. This measurement is taken internally between the two lugs using a digital calliper, and is the essential parameter for selecting a compatible strap that fits without play or friction.

For an 18-carat Everose gold case such as that of the 279135RBR-0026, the most suitable materials are alligator belly in bordeaux, cognac, or dark chocolate, shell cordovan for those seeking a progressive patina, and smooth calf leather in black or navy for formal settings. A rose gold buckle or deployant clasp completes the metallic pairing with consistency. The correct lug width to specify is 14 mm.

To replace the strap on the Lady-Datejust 279135RBR-0026, you will need a precision flat-head screwdriver or a proper springbar tool to remove the springbars without scratching the gold lugs. Work on a soft, anti-static surface. If in doubt, Casati Milano offers in-atelier strap fitting by appointment.

Yes. Any strap with a 14 mm attachment width is technically compatible with the Lady-Datejust 279135RBR-0026. Milano Straps offers a curated selection of artisan straps in various leathers and colours, hand-stitched and made specifically for this lug size, with customisable closure options including a classic buckle or deployant clasp.

Longevity depends on the leather, frequency of use, and maintenance. A vegetable-tanned alligator or shell cordovan strap, rotated with a second strap and kept away from water and direct perfume contact, can last between three and six years while developing a distinguished patina. Smooth calf leather typically lasts one to three years with daily wear. Casati Milano provides an 18-month warranty against manufacturing defects on all atelier-made straps.
