Strap for Datejust 31 Rolesor Everose Fluted / Oyster / Pink

The Rolex Datejust 31 ref. 178271-0001 has a lug width of 16mm. This measurement is specific to the 31mm case size and determines aftermarket strap compatibility. It is advisable to verify the internal distance between the lugs with a calliper before purchasing a replacement strap.

For the Oystersteel and Everose bimetallic combination of the Datejust 31, alligator hornback straps in cognac or dark burgundy tones offer the most coherent aesthetic pairing. Shell cordovan develops a patina that naturally complements the warm tone of rose gold. For everyday wear, vegetable-tanned calf leather in tobacco brown is a robust and versatile option.

The strap on the Datejust 31 is secured to the lugs via 16mm springbars. Replacement requires a springbar tool: insert the forked tip between the strap and lug, compress the springbar and slide it free. The operation can be completed in minutes without a watchmaker, provided care is taken not to scratch the case.

Yes. Milanostraps.it offers a selection of handcrafted straps with a 16mm lug width, compatible with the Datejust 31 178271-0001.

Lifespan depends on material and use. A quality alligator strap, worn regularly but not during sport, maintains structural and aesthetic integrity for 3 to 5 years. Vegetable-tanned calf leather typically lasts 2 to 3 years with daily wear. Avoiding prolonged contact with water, perspiration and perfume significantly extends the leather's life. Milano Straps products carry an 18-month warranty against manufacturing defects.
