Strap for 1966 36mm Stainless Steel / Pink Gold / Diamond / Silver / Alligator

The lug width of the Girard-Perregaux 1966 reference 49523D56A171-CB6A is 20 mm. This is measured from the inner edge of one spring bar attachment point to the inner edge of the opposite attachment, a specification standard across Girard-Perregaux heritage models in this line. All 20 mm straps are compatible with this timepiece.

For this 36 mm rose gold model, we recommend straps in dark brown alligator, vegetable-tanned leather with refined grain, or natural cotton NATO. Alligator emphasises elegance through its faceted texture, leather maintains formal discretion, whilst NATO creates an intentional contrast. We advise against synthetic rubber or artificial leather: rose gold deserves superior construction quality.

To remove the strap, use a quality spring bar tool with a fine tip. Insert the tip into the small lateral groove of the spring bar, apply gentle downward pressure, and pull the bar towards you with your other hand. The spring will retract, freeing the lug. Repeat on the opposite side. For installation, insert one end of the new strap first, then use the tool to gently compress the spring whilst inserting the second end. Never force: the operation should be smooth and precise.

Yes, absolutely. Any 20 mm strap is compatible with this reference, provided the construction quality matches the value and elegance of the rose gold case. We recommend artisanal straps made using traditional methods—vegetable-tanned leather, hand-finished, souple stitching—rather than generic industrial production. A high-quality strap will enhance and prolong the aesthetic pleasure of your Girard-Perregaux.

A quality leather strap, made from vegetable-tanned leather, typically lasts 3–5 years with regular wear. Longevity depends on frequency of use, sunlight exposure, humidity and maintenance. If you condition the strap with natural oils monthly and store it away from direct light when not worn, you can extend its life to 6–7 years. Cotton NATO straps, conversely, last 2–3 years before visible wear appears, offset by their simplicity and ease of replacement.
