Strap for Datejust 31 Everose Domed / President / Brown MOP Roman

The Rolex Datejust 31 reference 178245f-0021 is fitted with 16-millimetre lugs. This dimension is specific to the ladies' 31mm case and ensures harmonious proportions between the case and strap. Always measure at the base of the inner lug for the most accurate measurement.

For the Datejust 31 in rose gold 178245f-0021, we recommend vegetable-tanned alligator straps, which develop a warm patina complementary to rose gold. Alternatively, Crain calf leather offers robustness and contemporary texture. Shell cordovan remains the choice for enthusiasts seeking evolved patina over time.

Changing the strap on the Datejust 31 requires a spring bar tool, a specific instrument for disengaging the springs that secure the strap to the lugs. Position the tool under the lug near the spring, apply gentle pressure and slide the strap out of the lugs. Reverse the procedure to attach the new strap. If unsure, consult a professional.

Absolutely. Any strap with a 16mm lug width is compatible with the Datejust 31 178245f-0021. What matters is choosing quality makers who respect dimensional tolerances and use noble materials. Artisanal straps allow aesthetic customisation whilst maintaining constructive reliability.

A quality leather strap, made with artisanal methods and vegetable tanning, has an average lifespan of 5-7 years under moderate use. Variables such as climate, sun exposure and frequency of wear influence longevity. Regular maintenance — avoid prolonged immersion and hydrate the leather periodically — extends the strap's useful life.
