Strap for Datejust 31 Rolesor Yellow Fluted / Oyster / Champagne Floral

The Rolex Datejust 31 178273-0093 has a lug width of 16mm. This measurement is specific to the 31mm case size and is not interchangeable with the more common 18mm or 20mm straps. When sourcing a replacement strap, it is essential to confirm it is manufactured natively at 16mm to ensure correct fitment.

For the Datejust 31 178273-0093 in yellow gold Rolesor, alligator straps in warm tones — cognac, bordeaux, or midnight blue — best complement the fluted gold bezel. Vegetable-tanned calfskin is the most versatile choice for daily wear, whilst shell cordovan offers outstanding durability and develops a distinctive patina over time. A deployant clasp in steel or yellow gold PVD completes the pairing with visual coherence.

The strap on a Datejust 31 is removed using a spring bar tool compatible with 16mm lug width. It is advisable to work on a soft surface to protect the case and crystal from scratches. Alternatively, the watch can be taken to a watchmaker or to the Casati Milano atelier, where strap changes are performed with proper tools and no risk to the Oyster case.

Yes. The aftermarket offers high-quality handcrafted straps compatible with the 16mm lug width of the Datejust 31 178273-0093. Milanostraps.it offers a curated selection of leather, alligator and technical material straps built specifically for this size, with hand-stitched finishes and integrated keepers. Build quality is comparable or superior to OEM straps in terms of durability and fit.

The lifespan of a leather strap depends on the hide type, maintenance and daily exposure. A quality vegetable-tanned calfskin strap typically lasts 2–4 years with daily wear, developing a personal patina over time. An alligator or shell cordovan strap, owing to the denser fibre structure, can last 5–8 years if kept away from prolonged moisture and periodically treated with neutral conditioning products.
