Frequently asked questions

What is the lug width of the Girard-Perregaux 1966 49525-53-631-BK6A?

The lug width (ansa width) of the Girard-Perregaux 1966 49525-53-631-BK6A is 20 millimetres. This dimension represents the external width between the two lugs protruding from the case: it is the fundamental parameter for purchasing a compatible strap. To verify correctly, insert a millimetre ruler perpendicularly between the lugs and measure the exact distance.

Which strap is most suitable for the Girard-Perregaux 1966 in white gold?

For the Girard-Perregaux 1966 in white gold, high-quality alligator represents the most coherent choice: its characteristic grain and ability to develop a noble patina over time make it ideal. Alternatively, shell cordovan subjected to vegetable tanning offers extraordinary colour depth, whilst premium calf (grain calf) allows broad chromatic variations whilst maintaining elegance and wear resistance.

How do you change the strap on the Girard-Perregaux 1966 49525-53-631-BK6A?

The strap is changed by extracting the lugs (spring bars) that secure the strap to the case, using specialised tools such as a spring bar tool. Insert the tip of the tool into the appropriate hole located adjacent to the lug, apply gentle lateral pressure to retract the internal spring, and the bar slides out from the case. Repeat the operation on the other side. Insert the new strap by aligning one bar first, then gently press the opposite side until the second bar engages completely.

Can I use an aftermarket strap compatible with the 20mm lug width?

Yes, absolutely. Any strap with a 20mm lug width is compatible with the Girard-Perregaux 1966 49525-53-631-BK6A. Premium aftermarket artisanal straps (alligator, shell cordovan, calf, NATO) represent an opportunity to personalise your timepiece according to your aesthetic preferences and use context, whilst maintaining maximum technical precision.

How long does a leather strap last on the Girard-Perregaux 1966?

The lifespan of a leather strap depends on the quality of the material and intensity of use. A first-rate alligator or vegetable-tanned shell cordovan typically lasts 3–5 years of moderate daily use. Premium calf maintains acceptable aesthetics for 2–3 years. Exposure to perspiration, moisture and ultraviolet rays accelerates ageing. Rotating between two or three straps significantly extends the useful life of each.
