Strap for Lady-Datejust 28 Rolesor Yellow Domed / Oyster / Silver Diamond

The Rolex Lady-Datejust 279163-0004 features a 28mm Oyster case with a lug width of 14mm. This measurement is taken with a calliper positioned between the two lugs at the springbar attachment point. It is a fixed, structural dimension of this case design and does not vary across different dial or bracelet configurations of this reference.

For the Lady-Datejust 279163-0004 in steel and yellow gold, the most suitable options are alligator leather in cognac or tobacco — which complements the warmth of yellow gold — and vegetable-tanned calf leather for those who prefer a leather that develops a patina over time. Shell cordovan is the choice for maximum resistance and natural lustre. A deployant clasp is preferable to a pin buckle to preserve the strap's shape over the long term.

Strap replacement requires a dedicated springbar tool, a forked instrument that compresses the springbar pins within the case lugs. This can be performed independently with the correct equipment, but on a yellow gold case it is advisable to entrust the operation to a watchmaker or specialist atelier to avoid scratching the polished lug surfaces. The 14mm diameter makes compatible springbars readily available.

Yes. The aftermarket offers 14mm straps compatible with the Lady-Datejust 279163-0004 in various materials: leather (alligator, calf, shell cordovan), rubber and fabric. Milano Straps offers a selection of handcrafted 14mm straps with tapered or straight ends and a range of finishes designed to respect the proportions of the 28mm case. Bespoke production through Casati Milano allows every detail to be personalised.

The lifespan of a leather strap depends on the material, care and frequency of use. A quality alligator strap, properly stored and rotated with other straps, can last between three and seven years while maintaining good structural integrity. Vegetable-tanned calf leather tends to soften over time developing a patina, while shell cordovan offers the greatest resistance to deformation. All Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
