Strap for 1966 38 Pink Gold Black / Diamond / Silver / Alligator

The lug width (or strap width) of the Girard-Perregaux 1966 49525D52A1A1-BK6A is 20 millimetres. This measurement represents the space available between the two vertical lugs of the case where the strap is attached. To verify it, position a ruler or calliper perpendicularly across the lugs: the strap must occupy this space exactly without any lateral overhang.

For the Girard-Perregaux 1966 49525D52A1A1-BK6A, the ideal material depends on your personal style and occasions of use. Alligator leather in dark brown or taupe tones is the most conservative and historically accurate choice, featuring a geometric grain that enhances the case's elegance. Calf leather with vegetable tanning offers a natural patina that develops over time. NATO fabric straps in cotton provide contemporary versatility. For daily practical wear, vulcanised rubber in black is a discreet and durable solution.

Changing the strap is a straightforward operation you can perform yourself or have done by a specialist atelier. You will need a spring bar tool: insert the flat lever into the slot beneath the lug, compress the internal spring, and slide the strap out. Repeat on the other lug, then insert the new strap by clicking the spring bars into position. If you prefer professional assurance, the Casati Milano atelier performs strap changes by appointment.

All straps with a 20mm lug width are compatible. Milano Straps offers a curated selection of artisanal leathers—alligator, vegetable-tanned calf, shell cordovan—and sports straps in NATO and vulcanised rubber, all available in 20mm width. Your choice depends on aesthetic preference and the type of occasion you wish to accommodate.

A leather strap's lifespan varies depending on the material, frequency of wear, and care. A quality artisanal alligator leather, vegetable-tanned, may last three to five years with continuous use. Calf leather, being more moisture-absorbent, typically lasts two to three years. To extend strap longevity, avoid prolonged exposure to sunlight, fresh water, and aggressive detergents. Periodically applying a specialist leather conditioner maintains flexibility and delays premature ageing.
