Strap for Lady-Datejust 28 White Gold - Diamond / President / Grey - Roman

The Rolex Lady-Datejust 279139RBR-0010 features a 28mm white gold case with a lug width of 14mm. This measurement refers to the internal distance between the case lugs at the point where the strap attaches. It is a fixed dimension inherent to the case design and cannot be substituted with adjacent sizes such as 13mm or 16mm without compromising both the aesthetic and functional alignment of the strap.

For the Lady-Datejust 279139RBR-0010 in white gold with a diamond-set bezel, the most coherent choice is a vegetable-tanned alligator strap, ideally with a glossy or semi-glossy finish to complement the precious materials of the case. Alternatively, smooth box-calf leather in black or nude offers refinement and longevity. Shell cordovan is a third option for those seeking character and durability. The strap must be precisely 14mm at the attachment point.

The strap on the Lady-Datejust 279139RBR-0010 is secured by spring bars housed within the lugs. A flat-tipped or forked spring bar tool is required to compress the spring bar ends and release the strap. It is advisable to work on a soft surface to avoid scratching the white gold case. Alternatively, a watchmaker or the Casati Milano atelier can perform the change in a matter of minutes during a personalised consultation.

Yes. The aftermarket offers 14mm straps compatible with the Lady-Datejust 279139RBR-0010 in a variety of materials. Milano Straps produces and selects handcrafted straps specifically calibrated for this lug width, with stitching, thickness and profiles suited to the 28mm case. It is essential to verify that the attachment width is exactly 14mm and that the strap thickness is proportionate to the original Rolex lugs.

The lifespan of a leather strap depends on the material, tanning method and daily use. A high-quality vegetable-tanned alligator strap, with proper care — avoiding prolonged contact with water and perspiration — typically lasts 3 to 5 years. Box-calf leather generally lasts 2 to 4 years. Shell cordovan, owing to its dense fibre structure, can exceed 5 years. Milano Straps offers an 18-month guarantee against manufacturing defects on all Casati Milano straps.
