Strap for Vintage 1945 XXL Large Date and Moonphases Pink Gold / Silver

The Girard-Perregaux Vintage 1945 25882-52-121-BB6B features 24-millimetre lugs. This lug width is specific to the 36mm version of the Vintage 1945 collection and was calibrated by Girard-Perregaux to maintain optimal proportional balance between the tonneau-shaped case diameter and visual presence on the wrist. The 24-millimetre measurement represents the ideal midpoint, avoiding both excessive slenderness that would compromise structural integrity and oversized lugs that would visually burden the overall composition.

For a masterpiece of Art Déco design in rose gold such as the 25882-52-121-BB6B, alligator leather represents the pinnacle choice: the reptile's natural texture, with its geometrically defined scales, enters direct dialogue with the tonneau case's architectural language. An alternative of considerable elegance is vegetable-tanned calf leather in deep brown tones, which develops a warm amber patina over time that harmonises with the rose gold. For more versatile applications, heavy-weave NATO straps or shell cordovan maintain formal dignity without sacrificing practical wearability.

Strap replacement is accomplished by disengaging the spring bar located at both lugs. Using a dedicated tool—available through professional watchmakers or supplied with specialist kits—compress the spring mechanism and withdraw the bar from its seat. Once both lugs are liberated, insert the new 24mm strap by engaging the bar within its new housings until an audible click confirms secure seating. Given the precious nature of the rose gold case, we recommend entrusting this procedure to a qualified watchmaker rather than attempting it independently.

Yes, the Vintage 1945 25882-52-121-BB6B is fully compatible with quality aftermarket straps featuring 24-millimetre lugs. Milano Straps maintains an extensive collection of 24mm straps in alligator, vegetable-tanned calf, NATO, and elastomer materials. Selecting an aftermarket strap affords the opportunity to vary your watch's aesthetic whilst maintaining perfect technical compatibility and superior constructional quality.

Leather strap durability depends upon material composition, frequency of wear, and climatic exposure. Premium-grade alligator or vegetable-tanned calf, worn regularly in non-excessively humid conditions, maintain structural and aesthetic integrity for eight to twelve years. Direct exposure to humidity, chlorine, or intense perspiration significantly shortens this timeline. Rotating between multiple straps and storing them in dry environments maximises longevity. The patina that develops over time is integral to the beauty of these materials and should not be mistaken for deterioration.
