Strap for Datejust 31 Everose Domed / President / Silver Diamond

The Rolex Datejust 31 178245f-0016 features a lug width of 16 millimetres. This is the measurement between the lugs of the case. To verify, measure with a digital calliper the distance between the two spring bar holes at 12 o'clock and 6 o'clock positions on the case.

For the Datejust 31 178245f-0016 in Everose gold, we recommend natural alligator with geometric grain texture, box calf in vegetable tanning (which develops patina over time), or shell cordovan for those seeking exclusivity. Avoid rubber and NATO straps: this model demands noble materials that complement the precious case.

Changing the strap on a Datejust 31 requires removal of the spring bars using a dedicated tool. Position the watch on a soft surface, locate the spring bar at the base of each lug, apply gentle vertical pressure to release it, then remove. Insert the new strap by aligning the spring bar and press until it clicks into place. If uncertain, seek professional assistance.

Yes, Milano Straps offers artisanal straps in 16mm lug width compatible with the Datejust 31. Casati Milano creates bespoke straps by appointment in their Milan atelier, allowing you to select the leather and follow each production phase. Online, ready-made models in alligator, calf, and shell cordovan are available with an 18-month warranty.

Lifespan depends on material, usage and maintenance. Quality alligator lasts 3–5 years with daily wear. Vegetable-tanned calf lasts 2–4 years, shell cordovan 3–6 years (more fragile but exclusive). Regular cleaning and avoiding prolonged sun or humidity exposure extend strap life.
