Datejust 31 178241-0060— lug 16mm

The Rolex Datejust 31 ref. 178241-0060 has a lug width of 16 mm. This measurement is specific to the 31 mm case size within the Datejust family and is essential for selecting a compatible aftermarket strap. To verify independently, use a digital calliper positioned internally between the two lugs, flush against the case, excluding the side flanges.

For the Datejust 31 178241-0060 with its mother-of-pearl dial and Rolesor Everose case, the most coherent materials are vegetable-tanned alligator for formal wear, box-calf leather for everyday elegance, and shell cordovan for those seeking an evolving patina over time. A deployant clasp in matching Everose gold is recommended to maintain metallic coherence and reduce wear on the strap at the keeper.

Strap replacement on the Datejust 31 requires a fine-tipped spring bar tool to release the spring bars from the lugs. Original Rolex spring bars have a diameter of 1.8 mm. It is advisable to work on a soft surface to avoid scratching the case. Alternatively, Casati Milano offers an in-atelier fitting service by appointment.

Yes. Any strap with a 16 mm attachment and standard spring bars is technically compatible with the Datejust 31 178241-0060. Milano Straps crafts bespoke leather, NATO and rubber straps specifically in 16 mm lug widths, with finishes and colours selected to complement the Rolesor Everose combination and the mother-of-pearl dial of this reference.

The lifespan of a leather strap depends on the material, tanning method and daily use. A vegetable-tanned alligator strap, with regular conditioning, can last between 3 and 7 years. Calf leather typically lasts between 2 and 4 years. Shell cordovan, owing to its dense and compact structure, is among the most durable options. Milano Straps provides an 18-month warranty against manufacturing defects on all handcrafted straps.
