Datejust 31 178274-0092— lug 16mm

The lug width of the Rolex Datejust 31 ref. 178274-0092 is 16mm. This measurement is certified by Rolex for this reference and determines compatibility with any aftermarket strap. It is essential to select straps with curved ends to properly fit the contour of the Oyster case.

For the Datejust 31 178274-0092 with its white gold bezel, alligator belly straps in black, midnight blue or chocolate represent the most coherent pairing with the model's formal character. Shell cordovan in burgundy or tobacco is a distinctive alternative for those who appreciate a personal patina developing over time. For everyday mixed use, vegetable-tanned calf leather offers comfort and durability.

To replace the strap on the Datejust 31, the spring bars securing the bracelet or strap to the Oyster case lugs must be removed. A dedicated springbar tool is inserted into the lug slot to compress the bar and release it. It is advisable to work on a protected surface to avoid scratching the case. If in doubt, the procedure can be carried out by a watchmaker or at the Casati Milano atelier.

Yes, there are numerous aftermarket straps compatible with the Datejust 31 178274-0092, provided they feature a 16mm lug width and curved ends to match the profile of the Oyster case. Milanostraps.it offers a curated selection of handcrafted leather, NATO and rubber straps in 16mm, made specifically with the correct curves for this model.

The lifespan of a leather strap depends on the material and care taken. A quality alligator strap worn daily has an average life of 2–4 years; shell cordovan, thanks to its dense fibrous structure, can exceed 5 years whilst developing a refined patina. Vegetable-tanned leather requires periodic treatment with neutral creams to maintain hydration and flexibility. All Casati Milano straps carry an 18-month guarantee against manufacturing defects.
