Strap for Rue Royale Stainless Steel / Black / Black Alligator

The lug width is 18mm. This measurement represents the distance between the two spring bars that connect the case to the strap. It is essential to verify this specification before purchasing an aftermarket strap to ensure a perfect fit without lateral play and to prevent tension that could damage the lugs.

Alligator in vegetable tanning is the supreme choice: natural asymmetric scales reference classical French aesthetics, and vegetable tanning develops patina over time, acquiring character and depth. If budget is limited, calf leather in vegetable tanning with fine grain is an authentic alternative. For daily versatility, a canvas NATO with natural silk stitching allows stylistic rotations; for humid environments, FKM rubber with micro-texture ensures durable grip.

Position the watch on a stable table with the case covered by a soft cloth. Locate the spring bar that runs horizontally through the lug on both sides. Using a dedicated tool (spring bar tool) or a small flat screwdriver, push the spring bar downward to free the old strap. Insert the new strap in the opposite position, ensuring both bars click into place. Check that there is no lateral play.

Yes, any strap with an 18mm lug width is physically compatible with the Rue Royale. However, aesthetic compatibility depends on material and colour choices: we recommend neutral tones (brown, black, navy, cognac) in natural leather or technical materials such as NATO and rubber. Glossy synthetics or vivid colours would create a visual antithesis with the brushed geometry of the case.

A high-quality leather strap (alligator or calf) with vegetable tanning and artisanal construction lasts 5–8 years with regular wear and ordinary maintenance. Longevity depends on frequency of use, climate, perspiration, and care: occasional rinses with fresh water and air drying extend the material's life. FKM rubber lasts 10–12 years without visible ageing.
