Strap for 1966 40 Stainless Steel Bracelet Diamond

The lug width of the Girard-Perregaux 1966 49555D11A131-11A is 18mm. This measurement is taken from centre to centre of the upper attachment points and is standard for European dress watches. It provides access to a broad range of specialised leather, rubber, and fabric straps.

For the Girard-Perregaux 1966, we recommend African alligator or vegetable-tanned calf leather straps. Alligator enhances the watch's formal restraint, whilst calf develops a natural patina over time. For more versatile daily wear, structured vulcanised rubber is a contemporary choice that maintains the watch head's visual balance.

To change the strap, use a spring bar tool to gently depress the closure button of the elastic pin. Maintain precise, controlled movement to avoid scratching the case. Insert the new strap into the lugs until you feel the spring mechanism's retention click. If uncertain, entrust the task to a professional watchmaker.

Yes, the Girard-Perregaux 1966 accepts any strap with an 18mm lug width. A quality aftermarket strap (alligator, calf, shell cordovan) guarantees perfect compatibility and often delivers aesthetic solutions superior to originals. Ensure the spring bars are in good condition and the strap is robust.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years with daily wear, depending on ambient humidity and frequency of use. Vegetable tanning develops a protective patina naturally over time, extending longevity. Prolonged water exposure shortens lifespan; we recommend drying the strap after incidental contact.
