The Lady-Datejust 279381RBR-0026, seen from the bench

The Rolex Lady-Datejust 28 Stainless Steel/Rose Gold/Diamond/Rose-Roman/Oyster (ref. 279381RBR-0026) represents a contemporary synthesis of the feminine Datejust line initiated in 1957. This two-tone model combines 18-carat Everose Gold with 904L steel and features a 28mm case with a diamond-set bezel, powered by the Rolex caliber 2236 (28,800 vibrations/hour). The case is water-resistant to 100 meters with a screw-down caseback, and features a specific 14mm lug width—a dimension that requires custom-fitted straps and is not interchangeable with standard 13mm or 16mm options.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279381RBR-0026?

The Rolex Lady-Datejust 279381RBR-0026 has a lug width of 14mm. This measurement should be taken with a calliper across the inner distance between the two lugs, and is essential for selecting any compatible aftermarket strap.

What is the best strap for the Rolex Lady-Datejust 279381RBR-0026?

For this Everose Gold reference with a diamond-set bezel, the most suitable straps are vegetable-tanned alligator — preferably in cognac, burgundy or slate grey — or fine-grained glacé calf leather for a more formal register. Shell cordovan is a refined choice for those seeking an evolving patina over time. All options must feature a 14mm attachment width.

How do you change the strap on a Rolex Lady-Datejust 279381RBR-0026?

Strap replacement is carried out via springbars, the spring-loaded bars housed within the lugs. A fine-tipped springbar tool is required to avoid scratching the Oystersteel or Everose Gold lugs. It is advisable to place the watch on a soft mat and work carefully. Alternatively, the operation can be performed at the Casati Milano atelier.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279381RBR-0026?

Yes. Milanostraps.it offers a selection of handcrafted straps with a 14mm attachment compatible with the Lady-Datejust 279381RBR-0026. Each strap is produced using selected materials — alligator, calf leather, shell cordovan — and can be made to measure at the Casati Milano atelier with a personalised colour pairing.

How long does a leather strap last on a Rolex Lady-Datejust?

Longevity depends on leather type and daily use. A quality vegetable-tanned alligator strap, worn with care — avoiding prolonged contact with water and perspiration — will retain its structural and aesthetic integrity for 3 to 5 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
