Strap for Villeret Manuelle Piece Unique Grande Décoration / Black Enamel

The lug width of the Blancpain Villeret 6615-3637-55B is 23mm. This measurement represents the distance between the inner attachments of the case and determines strap compatibility. It is essential to measure it correctly by positioning a digital calliper between the two inner lug shoulders, not on the exterior surface. An incorrect measurement risks purchasing an incompatible strap.

For the Villeret 6615-3637-55B in rose gold, we recommend alligator or vegetable-tanned calf leather. Alligator offers a natural texture that dialogues elegantly with the noble metal, developing patina over time. Vegetable-tanned calf imparts artisanal authenticity and visible ageing that progressively transforms the colour. Both materials avoid competing with the formal sobriety of the dial and skeletonised movement.

To change the strap, position the watch with the dial facing downward on a soft surface (microfibre cloth). Use a dedicated spring bar tool to remove the steel spring bars from the lugs: insert the forked tip of the tool into the longitudinal slot of the spring bar, press inward and downward simultaneously to release the spring tension. Extract the old strap, verify the spring bars' integrity, then install the new strap by reversing the procedure. We recommend entrusting this operation to a professional watchmaker to prevent case damage.

Yes, you may use a quality aftermarket strap provided it respects the 23mm lug width. We recommend straps manufactured by specialised artisans that guarantee aesthetic coherence with rose gold and respect proper proportional design. Avoid low-quality generic straps: the Villeret 6615-3637-55B deserves noble materials and consistent finishing. Always verify spring bar compatibility—typically polished steel or rose gold—with the case finishing.

A high-quality leather strap (alligator, vegetable-tanned calf, shell cordovan) on a regularly worn luxury watch typically lasts 3–5 years, with variations depending on personal use and climatic conditions. Exposure to perspiration, humidity and UV light accelerates wear. A well-maintained strap, protected from excessive moisture and rotated with other options, may last up to 7 years. We recommend having the strap inspected annually by a watchmaker to assess the buckle, spring bars and stitching condition, and perform preventive leather rejuvenation treatments.
