Strap for Datejust 31 Rolesor Everose Domed / Jubilee / Purple Roman

The lug width of the Datejust 31 178241-0071 is 16mm, which is the distance between the two lugs where the strap is attached to the case. This is a non-standard measurement requiring bespoke artisanal straps, incompatible with common 18mm or 20mm options.

Alligator is the most harmonious choice, as its natural texture and uniform grain complement the steel and rose gold case perfectly. Shell cordovan with vegetable tanning is also exceptional, developing a rich patina over time. Fine calf leather in craie finish offers a more contemporary alternative.

Changing the strap requires a spring bar removal tool to avoid damaging the rose gold case. Gently push the internal spring with the tool, extract the elastic bar, and replace the strap. If uncertain, consult a certified watchmaker or Casati Milano.

Yes, provided the lug width is exactly 16mm. Milano Straps offers bespoke artisanal straps for this reference in alligator, calf, shell cordovan and other premium materials. Each strap is tested for mechanical compatibility.

A quality alligator or shell cordovan strap typically lasts 3-5 years of daily wear, depending on wear rate in the flex area and cleaning frequency. Vegetable-tanned leather ages gradually, developing character. Milano Straps provides an 18-month warranty against manufacturing defects.
