Strap for 1966 40 Stainless Steel Bracelet

The lug width of the Girard-Perregaux 1966 49555-11-1A1-11A is 18mm. This measurement is determined by the geometry of the 40mm case and the curvature of the lugs. To verify strap compatibility, measure the internal space between the two lugs: it must be exactly 18mm.

The Girard-Perregaux 1966 49555-11-1A1-11A pairs ideally with straps in vegetable-tanned alligator, structured calf leather, or cotton NATO. Avoid overly rigid materials or aggressive textures: the model requires straps that accommodate the delicate curve of the lugs without compromising the sober geometric aesthetics of the original design.

Strap replacement requires a specialised tool to extract the spring bars. Position the watch with the lugs facing upward, locate the small hole at the base of each pin, and apply controlled pressure to release the internal spring. Remove the old strap and insert the new one, ensuring the pins click firmly at both ends. If unsure, Casati Milano offers professional strap-change services in their atelier.

A vegetable-tanned leather strap for the 49555-11-1A1-11A typically lasts 3-5 years with moderate daily use, developing a natural patina that enhances character. Longevity depends on moisture exposure, perspiration, and mechanical wear. Vegetable-tanned alligator straps last longer; cotton NATO straps require less maintenance but are more susceptible to fibre wear. FKM rubber straps offer the greatest durability, lasting up to 7-8 years.
