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

The lug width of the Girard-Perregaux Vintage 1945 25882-52-222-BB6B is 24mm. This dimension reflects the original proportions of the 36.10mm tonneau case and is critical for proper aesthetic integration. Measure manually the distance between the lug ears where the strap attaches to verify absolute compatibility.

For this pink gold case, we recommend straps in toasted alligator, vegetable-tanned calf in cognac or bordeaux tones, or shell cordovan. Avoid textiles that compromise the case's vertical proportions. A brown alligator strap creates the most natural chromatic dialogue, whilst honey-coloured calf develops golden patina that harmonises with the gold over time.

The strap is changed by unscrewing the spring bar attachments linking the strap to the case. Use a dedicated spring bar tool to compress the internal spring mechanism and extract the old lug. Insert the new strap by aligning its holes with the case's lug ears and gently release the spring bar. Proceed with precision: the pink gold case deserves handling that prevents accidental scratching.

Any strap with spring bar attachments specifically sized for 24mm lug width is compatible. Milano Straps maintains specialised catalogues of alligator, calf, shell cordovan and rubber for this exact dimension. Always verify the strap is constructed for 24mm: a 2mm error creates excessive tension or loose fitment, both unacceptable on a piece of this calibre.

A quality artisanal calf strap withstands 18–36 months of daily wear before requiring replacement, depending on usage intensity and care. Shell cordovan, being denser, reaches 4–5 years. Vegetable-tanned leather develops fascinating patina during this period. Alligator, more delicate, requires periodic rotation with alternative straps to extend lifespan beyond 2 years.
