Frequently asked questions

What is the lug width of the Rolex Datejust 31 278288RBR-0038?

The Rolex Datejust 31 reference 278288RBR-0038 features a lug width of 16 millimetres. This dimension is specific to the 31mm case and represents a critical element when selecting a compatible strap: even minimal deviation results in visual and functional discrepancy.

Which strap is most appropriate for a rose gold Datejust 31?

High-quality alligator in dark shades (dark brown, black) represents the canonical choice. Vegetable tanning offers a sophisticated alternative for those accepting visible patina development. Shell cordovan provides exceptional durability. Selection depends on tolerance for visible ageing and frequency of use: structured alligator maintains formal elegance with minimal maintenance.

How do you change the strap on a Rolex Datejust 31?

The Rolex strap is secured via spring bars positioned at the lug ends. Strap removal requires a dedicated tool (spring bar tool) and careful handling to avoid case scratching. A specialised atelier performs this operation within minutes without risk of damage.

Are aftermarket 16mm straps compatible with the 278288RBR-0038?

Yes, any strap with 16mm lug width is compatible, provided the leather quality and buckle (or deployante) finishing are proportional to the watch's value. Milano Straps offers bespoke handcrafted straps in this dimension, verified for absolute compatibility.

How long does a leather strap last on a Datejust 31 with daily wear?

A high-quality alligator strap, with moderate daily use (avoiding shower/pool exposure), lasts 5-7 years before replacement becomes necessary. Vegetable-tanned leather ages more rapidly visually but remains functional. Regular maintenance (cleaning, conditioning) significantly extends durability.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
