Lady-Datejust 279136rbr-0009— lug 14mm

The Rolex Lady-Datejust 279136RBR-0009 has a lug width of 14mm. This measurement is specific to the 28mm case variant and is not interchangeable with straps designed for the 36mm or 41mm Datejust references. Always verify with a digital calliper before purchasing a replacement strap.

For a platinum 950 case set with a diamond bezel, the most appropriate materials are belly alligator in neutral tones (slate grey, midnight blue, ivory white) or smooth vegetable-tanned calf leather. Rubber is preferable for sporting or warm-weather use. A steel or platinum deployant clasp is recommended to extend the lifespan of a leather strap.

The strap is removed using a spring bar tool, carefully leveraging the spring bar within the lug channel. Work on a soft surface to avoid scratching the platinum case. Alternatively, any qualified watchmaker or the Casati Milano atelier can perform the swap in a matter of minutes.

Yes. The aftermarket offers high-quality straps compatible with the 14mm lug width of the 279136RBR-0009. It is essential that the strap features a curved end to match the Oyster case profile. Milano Straps offers a curated selection of handcrafted 14mm straps tailored to this specific reference.

The lifespan of a leather strap depends on the material and conditions of use. A quality alligator strap, kept away from prolonged water and perspiration exposure, typically lasts between two and four years. Vegetable-tanned calf and shell cordovan develop a fine patina over time while offering excellent durability. Casati Milano straps come with an 18-month production defect warranty.
