Strap for Rolex Datejust 31 278241

The lug width is exactly 16 millimetres. This width is specific to the Datejust 31 (31mm case diameter) and is not compatible with 14, 18, or 20 millimetre straps. To verify, position a calliper between the shoulders of the upper and lower case attachments.

Dark brown alligator is the classic choice that enhances the Everose rose gold. Vegetable-tanned calfskin develops natural patina over time. Shell cordovan is a rare and prestigious alternative. For sports contexts, nylon NATO fabric guarantees water resistance. FKM rubber is ideal for aquatic environments.

Position the watch face-down on a soft surface. Locate the connecting pins between case and strap (one per side). Use a dedicated tool (spring bar tool) to compress the pin and release it from the hole. Repeat on the other side. Insert the new strap by aligning the pins and pressing until they click into place.

Yes, any strap with a 16 millimetre lug width is compatible. Always verify the width before purchase. Custom artisanal straps offer greater precision: they are crafted with correct pins and guarantee optimal fit without gaps between strap and case.

A quality alligator strap lasts 3–5 years with daily wear, depending on environment (humidity, perspiration, water exposure). Vegetable-tanned leather ages visually better. To extend lifespan, avoid prolonged salt water exposure and periodically hydrate with neutral creams. Production defect warranty is typically 18 months.
