Strap for 1966 Annual Calendar Equation of Time Pink Gold

The lug width of the Girard-Perregaux 1966 49538-52-131-BK6A is 20mm. This standard represents the symmetrical space between the two lugs and is essential to ensure a perfect fit with any artisanal strap. Measurement should be taken from the outer edge of one lug to the other using a digital precision calliper.

For this rose gold case, dark brown or cognac alligator is the most natural choice: the texture of the leather dialogues perfectly with the luminosity of the precious metal. Alternatively, vegetable-tanned calf leather that develops patina over time creates an elegant and versatile pairing. For sportier contexts, a NATO strap in discrete tones remains fully compatible with the formal aesthetics of the model.

The strap is changed using a specific tool (pin remover or spring bar tool). It is necessary to gently remove the pins that connect the strap to the case lugs. If you do not have the appropriate tool, it is advisable to have the operation performed by a specialist watchmaker, especially for watches of high value such as this Girard-Perregaux.

Yes, any strap with a 20mm lug width is compatible with the 49538-52-131-BK6A. High-quality artisanal straps, such as those in alligator, vegetable-tanned calf, NATO and rubber, fit perfectly to the lugs of this model, provided they respect the precise 20mm measurement.

The durability of a leather strap depends on the quality of the material, the type of tanning and the frequency of wear. Artisanal-quality alligator or calf leather, with vegetable tanning, typically lasts 3-5 years if worn daily; if worn occasionally, the lifespan extends to 7-10 years. The patina that develops imparts character to the strap over time.
