Strap for Lady-Datejust 28 Rolesor Yellow Fluted / Jubilee / Silver Diamond

The Rolex Lady-Datejust 279173-0007 features a 28mm Oyster case with a lug width of 14mm. This measurement is taken between the inner faces of the lugs at the point where the strap attaches to the case, and should be verified with a digital calliper. This dimension is specific to the 28mm Lady-Datejust range and is not interchangeable with 18mm or 20mm straps.

For the Lady-Datejust 279173-0007 in yellow Rolesor, an alligator strap in cognac or tobacco tones offers the most coherent pairing with the 18-carat yellow gold components. Vegetable-tanned calf leather in burgundy or bordeaux is well-suited to daily use. For warmer months or sporting occasions, vulcanised FKM rubber provides comfort and durability without compromising the refined aesthetic of the 28mm case.

Strap replacement requires a fine-tipped springbar tool to remove the 14mm spring bars connecting the strap to the Oyster case lugs. It is advisable to work on a soft surface to protect the sapphire crystal and fluted bezel. Those unfamiliar with precision timepiece servicing are recommended to consult a watchmaker or contact the Casati Milano atelier directly.

Yes, the aftermarket offers 14mm straps fully compatible with the Lady-Datejust 279173-0007. Milano Straps curates a selection of handcrafted options with curved ends tailored to the radius of the 28mm Oyster case, available in alligator, calf leather, NATO and rubber. Compatibility is determined solely by the 14mm lug width and the curvature of the strap ends, irrespective of the strap brand.

The longevity of a leather strap depends on leather quality, frequency of use and daily care. A high-grade alligator or vegetable-tanned calf strap, kept away from excessive moisture and perspiration and conditioned periodically, can last between three and five years with regular wear. Casati Milano provides an 18-month manufacturing warranty on all bespoke straps.
