Strap for Datejust 31 Stainless Steel/ Rose Gold / Domed / Rose - Roman / Jubilee

The lug width of the Rolex Datejust 31 ref. 278241-0006 is 16mm. This measurement is taken between the two lugs using a digital calliper and is the essential parameter for selecting a compatible strap. It should not be confused with the 20mm of the Datejust 41 or the 17mm found on other references within the same family.

For the Datejust 31 278241-0006 in Oystersteel and Everose gold, the most suitable straps are alligator in polished black for formal occasions, vegetable-tanned calfskin in cognac or burgundy tones for refined daily wear, or shell cordovan in burgundy for a warm, tailored pairing. A deployant clasp in steel or rose gold completes the combination with metallic coherence.

To replace the strap on the Datejust 31 278241-0006, a dedicated springbar tool or fine-tipped lever is required to remove the spring bars from between the lugs. The operation demands care to avoid scratching the Oyster case: it is advisable to rest the watch on a soft cloth and work under adequate lighting. Alternatively, the Casati Milano atelier performs strap fitting by appointment.

Yes, a wide range of aftermarket 16mm straps are compatible with the Rolex Datejust 31 278241-0006. Milanostraps.it offers a curated selection of handcrafted straps made specifically for this lug width, available in various leathers and finishes. It is essential to verify that the attachment width is exactly 16mm and that the spring bars are either included or compatible with the original ones.

The lifespan of a leather strap depends on the material, frequency of use and level of care. A quality alligator strap, periodically treated with a nourishing cream and stored away from moisture, can last between 3 and 5 years with regular wear. Vegetable-tanned calfskin develops an attractive patina but is more susceptible to humidity. Shell cordovan is among the most resilient and longest-lasting options. Casati Milano offers an 18-month warranty against manufacturing defects on all straps.
