Strap for Lady-Datejust 28 Stainless Steel / Diamond / White - Roman / Oyster

The lug width of the Rolex Lady-Datejust 279384rbr-0020 is 14 mm. This measurement is taken between the two lugs at the point where the strap attaches to the case, using a digital calliper or precision ruler. Adhering to this dimension is essential to ensure a correct fit without lateral play.

For this white gold and diamond reference, an alligator belly strap with vegetable tanning in ivory, slate grey or bordeaux tones is the most coherent choice given the calibre of the piece. Alternatively, a white or smoke grey box-calf strap with a polished steel deployant clasp provides everyday elegance while protecting the lugs over time.

Strap replacement requires a fine-tipped springbar tool inserted into the slot between the lug and the spring bar, compressing the spring bar ends. Work with the watch resting on a soft cloth to avoid scratching the case. It is advisable to have the operation carried out by a watchmaker or by the Casati Milano atelier for a professional fitting.

Yes. Aftermarket straps with a 14 mm lug width and standard spring bars are fully compatible. Milano Straps crafts handmade straps with hand-finished ends specifically proportioned for the Lady-Datejust, available in alligator, calf leather, NATO and rubber. Compatibility is determined by the lug width, not by the strap's origin.

A quality handcrafted leather strap with vegetable tanning and hand-finished edges has an average lifespan of 2–4 years with daily wear, depending on exposure to perspiration, water and UV light. Rotating between two straps significantly extends the life of both. Milano Straps provides an 18-month warranty against manufacturing defects.
