Strap for 1966 38 White Gold / Silver / Alligator

The lug width of the Girard-Perregaux 1966 reference 49525-53-131-53A is exactly 20 mm. This measurement corresponds to the distance between the two horizontal lugs on the case. A compatible strap must measure precisely 20 mm in width to ensure perfect alignment with the case.

For a watch of this calibre in white gold, we recommend alligator or vegetable-tanned calf leather. Alligator offers natural grain and develops patina over time; calf leather guarantees austere elegance and softness. For daily wear, NATO or rubber provide practicality whilst maintaining a sober aesthetic consistent with the model's minimalist design.

The procedure is straightforward with the correct tools: a spring bar tool or dedicated strap removal instrument. Remove the horizontal pins connecting the strap to the case, detach the old strap, insert the new one in the same orientation, and reinsert the pins. If you prefer to avoid the risk of scratching the case, a professional watchmaker completes the operation in minutes.

Yes, any strap manufactured to the 20 mm standard is mechanically compatible with the 49525-53-131-53A. Aesthetic compatibility, however, depends on material, colour, and finish: we advise against synthetic straps or overly polished finishes, which would compromise the design's sobriety. Opt for natural leather and vegetable tanning to maintain harmony with the case's white gold.

A high-quality leather strap—alligator or vegetable-tanned calf—typically lasts 5–8 years with regular daily wear. Longevity depends on exposure to moisture, perspiration, direct sunlight, and maintenance frequency. Shell cordovan, owing to its natural density, can reach 10 years. Applying a protective treatment every 6–12 months significantly extends the strap's lifespan.
