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

The Rolex Lady-Datejust 279163-0006 has a lug width of 14mm, measured internally at the base of the lugs. This specification is particular to the 28mm variant and differs from larger Datejust references. We recommend verifying the measurement with a digital calliper before ordering a replacement strap.

For the Lady-Datejust 279163-0006 in yellow Rolesor, an alligator strap with vegetable tanning in cognac or bordeaux is the most coherent choice for the formal register of the piece. Box-calf leather offers a more accessible yet equally elegant alternative. In either case, the buckle or deployant clasp should be in gold-toned steel to maintain chromatic continuity with the yellow gold bezel.

Strap replacement requires a precision spring bar tool with a 0.8mm tip compatible with the Lady-Datejust spring bars. The 28mm lugs have a downward-curved profile: the replacement strap must feature shaped ends specifically worked to match this geometry. It is advisable to work on a soft surface with adequate lighting to avoid scratching the Rolesor case.

Yes. The aftermarket offers 14mm straps compatible with the Lady-Datejust 28mm, provided they are made with shaped ends suited to the Oyster lug profile. Milano Straps produces handcrafted straps specifically dimensioned for this lug width, available in alligator, calf leather, shell cordovan and other materials, with bespoke options through the Casati Milano atelier.

Longevity depends on material, frequency of use and maintenance. A quality vegetable-tanned alligator strap worn daily has an average lifespan of 2–4 years before the inner fibre shows structural signs of fatigue. Calf leather degrades more rapidly when exposed to perspiration and humidity. Rotating between two straps significantly extends the life of both. Milano Straps products carry an 18-month warranty against manufacturing defects.
