Strap for Lady-Datejust 28 Platinum Diamond / President / Silver Diamonds

The Rolex Lady-Datejust 279136RBR-0003 features a 28mm case with a lug width of 14mm. This dimension is less common in the mainstream strap market and therefore requires straps specifically made or selected for the 14mm format, ensuring a precise fit without lateral play between the lugs.

For a platinum 950 case with a diamond-set bezel, the ideal strap is a glossy alligator belly in deep navy, black or bordeaux, able to complement the nobility of the metal without overpowering the gem-set bezel. Box-calf vegetable-tanned leather and shell cordovan are highly characterful alternatives. For sporting or aquatic use, bespoke vulcanised rubber is the most functionally coherent option.

The strap is removed using a spring bar tool inserted into the lug slots to compress the spring bar ends and release the strap. It is advisable to carry out the operation on a soft surface to protect the platinum case from scratches. If in any doubt, it is preferable to entrust the operation to a qualified watchmaker or strap specialist.

Yes. The 14mm format is produced by specialist craftsmen such as MilanoStraps, which offers aftermarket straps in alligator, calf leather, cordovan and rubber made to measure for this lug width. High-quality artisan aftermarket straps can equal or exceed the original strap in terms of comfort, patina and longevity, provided they respect the dimensional tolerances of the Lady-Datejust 14mm lug.

The lifespan of a leather strap depends on the material, frequency of wear and the care given to it. A quality alligator strap, rotated with others and kept away from prolonged moisture and perspiration, can last between 3 and 7 years while maintaining a well-kept appearance. Vegetable-tanned calf leather develops a characteristic patina over time but is more susceptible to water. The 18-month guarantee offered by Casati Milano covers manufacturing defects.
