Frequently asked questions

What is the lug width of the Girard-Perregaux 1966 49535-53-152-BK6A?

The lug width is 20mm. This width is specific to dress watches of this category and is measured as the distance between the lug interstices, not their total length. It is essential to verify this measurement before ordering an aftermarket strap to ensure proper fit without backlash.

What strap material is recommended for the Girard-Perregaux 1966 49535-53-152-BK6A?

For a white gold watch of this calibre, alligator in neutral tones (chocolate brown, black, deep burgundy) represents the most conservative choice and develops natural patina over time. Vegetable-tanned calf leather offers a more dynamic alternative with visible ageing characteristics, whilst cordura NATO straps provide informal practicality, and rubber solutions maintain formal dignity.

How do you change the strap on the Girard-Perregaux 1966 49535-53-152-BK6A?

Strap replacement is achieved through the spring bars positioned within the lug interstices. Using a dedicated spring bar tool, compress the outer pin to release one strap end, then repeat the procedure for the opposite side. This process requires delicacy to avoid scratching the white gold case. Professional assistance from sartorial ateliers such as Casati Milano is recommended.

Is an aftermarket strap compatible with the Girard-Perregaux 1966 49535-53-152-BK6A?

Yes, provided the strap is specifically manufactured for 20mm lugs. Milano Straps offers a comprehensive selection of leather, NATO, and rubber straps certified for this width, guaranteeing immediate compatibility and seamless transition with the case lugs.

What is the lifespan of a leather strap for the Girard-Perregaux 1966 49535-53-152-BK6A?

A quality alligator or calf leather strap, used daily, maintains structural and aesthetic integrity for 3-5 years. Durability depends on keeper wear, ambient humidity, and frequency of use. Vegetable tanning permits minor restoration (patina reconditioning) without compromising the strap's overall functionality.
