Strap for Datejust 31 Stainless Steel Fluted / Oyster / Pink - Diamond

The lug width of the Rolex Datejust 31 278274-0031 is 16 millimetres. This specification is essential for purchasing a compatible strap: any other width will render the strap unusable. To verify with certainty, position a digital calliper between the two lugs at the exact attachment point where the original strap connects to the case. Should your example differ, contact our team prior to ordering.

For this noble material combination, we recommend first choice vegetable-tanned alligator in cognac or deep brown, which amplifies the luminosity of the white gold without visual heaviness. Secondary option is shell cordovan in pearl grey or black – a material that develops a particularly refined patina with age. For daily wear, vegetable-tanned calf leather in burgundy represents an elegant compromise between formal and practical. We advise against synthetic materials or uniform gloss finishes, which do not dialogue well with the case's sophistication.

The procedure requires a specific spring bar removal tool. Position the watch on a soft surface, identify the two lateral pins at the lugs, insert the tool into the lateral hole in the case and apply gentle pressure: the pin extracts from the opposite side. Once both pins are removed, the original strap separates; thread the new strap by inserting the pins from one side and ensuring they seat completely on both sides. If unfamiliar with the procedure, your local watchmaker will perform the operation in minutes at minimal cost.

Yes, provided it is manufactured for 16-millimetre lug width. The reference 278274-0031 imposes no proprietary standard on width specification: any artisanal strap, if correctly measured at 16mm, adapts perfectly. Always verify the measurement with your supplier. Casati Milano straps, hand-stitched and finished, offer guaranteed compatibility and manufacturing quality superior to industrial products.

A quality vegetable-tanned leather strap, such as those crafted by Casati Milano, maintains function and aesthetics for 3–5 years with daily wear. Longevity depends on usage (climate, perspiration, wearing frequency) and maintenance (periodic cleaning, drying after water contact). Vegetable-tanned leathers develop natural patina that adds character rather than representing degradation. In the event of premature structural damage, the 18-month guarantee covers manufacturing defects.
