Strap for 1966 Annual Calendar Equation of Time Pink Gold Bracelet

The lug width of the Girard-Perregaux 1966 49538-52-131-52A is 20mm. This dimension is determined by the case construction and its terminal lugs; every strap must be manufactured according to this exact measurement to ensure a perfect interface between the lug and the strap's lug keeper.

The best strap depends on the intended use. Natural alligator or vegetable-tanned cordovan amplify the classical elegance of the pink gold timepiece, maintaining a coherent chromatic palette. A grey tortoiseshell NATO or a structured black rubber strap represent contemporary alternatives for those wishing to hybridise the formal character of the watch with greater versatility.

To change the strap, use a specialised spring bar removal tool. Position the watch on a stable surface, locate the small holes inside the lugs, insert the tool to compress the spring, then extract the old strap. Repeat for the lower lug. Installation of the new strap follows the reverse procedure: align the spring bars, compress gently, and verify that the spring is correctly positioned.

Yes, all 20mm lug width straps are compatible with the Girard-Perregaux 1966 49538-52-131-52A, provided they are manufactured to adequate quality standards. Artisanal straps in alligator, shell cordovan, NATO and technical rubber are valid alternatives and often superior in aesthetic terms compared to original straps, as they permit customisation of chromatic palette and finishing.

The longevity of a leather strap depends on material quality and usage regime. An alligator or vegetable-tanned cordovan, worn daily but with care, maintains structural integrity for 5-7 years. Frequent exposure to humidity, perspiration and direct sunlight significantly reduces this duration. Periodic maintenance—cleaning and light conditioning—substantially extends strap lifespan.
