Datejust 31 178341-0033— lug 16mm

The lug width of the Datejust 31 178341-0033 is 16 mm. This is a non-standard width, characteristic of Rolex women's models, requiring bespoke straps. It is not compatible with universal 18 mm or 20 mm straps.

For the Everose Rolesor, we recommend alligator or shell cordovan. Alligator (fine grain, regular pattern) amplifies the refinement of the two-tone case without visual competition. Cordovan develops a soft patina that harmonises beautifully with the warm tone of rose gold. Vegetable-tanned calf leather suits those seeking a more rustic, naturally textured aesthetic.

The Datejust 31 is fitted with a Rolex deployante clasp (typically engraved with the reference number). To replace the strap: 1) Remove the watch from your wrist; 2) Slide the deployante release mechanism to detach the original strap; 3) Insert the new strap into the lugs (pins) of the case, ensuring proper alignment; 4) Secure the deployante by engaging it until you feel a distinct click. If uncertain, consult an authorised Rolex service centre.

Yes, provided they respect the 16 mm lug width. Bespoke straps from specialised ateliers such as Casati Milano offer full compatibility with original Rolex pins. Avoid budget universal straps: construction quality and finishing must reflect the calibre of the timepiece.

A quality leather strap (alligator, cordovan, calf), worn daily, maintains structural and aesthetic integrity between 18 and 36 months, depending on frequency of wear, sun exposure and climatic conditions. Vegetable-tanned leather tends to age more gracefully than synthetic tanneries. With Casati Milano, every strap includes an 18-month warranty against manufacturing defects.
