Datejust 31 278273-0014— lug 16mm

The lug width of the Rolex Datejust 31 278273-0014 is 16mm. This dimension is specific to the 31mm ladies' model and ensures balanced optical proportions relative to the case. Verify this measurement by inserting a ruler between the case and your current strap to obtain the exact physical depth of the space to be covered.

For the Datejust 31 Rolesor, the following materials are recommended: alligator with straight grain for maximum sophistication; vegetable-tanned leather with press grain that develops patina over time; shell cordovan for superior durability and colour palette ranging from burgundy to dark brown. Avoid technical materials such as rubber or NATO, which contradict the formal stylistic identity of the model.

Strap replacement requires specific tools: a spring bar tool to push the lateral pins of the case and release the lugs. It is strongly recommended to contact an authorised Rolex service centre or qualified professional to avoid case damage. For bespoke work, Casati Milano performs this operation in atelier and follows the client via WhatsApp throughout the entire process.

Yes, any strap with a 16mm lug width is technically compatible. However, construction quality and aesthetic choice are essential: a certified artisanal strap with standard pressure passants guarantees superior durability and stylistic coherence compared to industrial straps. Technical compatibility does not imply quality compatibility.

Durability depends on material and use: vegetable-tanned calf lasts an average of 5-7 years under daily use conditions, with natural patina development; high-grade alligator reaches 7-10 years; shell cordovan exceeds 10 years. Greater wear concentrated at the buckle or deployant closing point is normal. Periodic maintenance (minimal oiling, cleaning) significantly extends useful life.
