Strap for Master Collection 44 Retrograde Pink Gold / Silver-Arabic / Alligator XL

The Longines Master Collection L2.717.8.78.5 features a lug width of exactly 20mm. This measurement is critical when purchasing a compatible strap: any alternative width (such as 19mm or 21mm) will not fit correctly onto the watch case lugs and will result in visible misalignment. Always verify with your strap supplier that the strap is explicitly certified for 20mm compatibility.

For a Longines Master Collection L2.717.8.78.5 in pink gold, I recommend alligator leather in navy blue or forest green (natural tones that echo the case's rosy warmth), or naturally aged calf leather with a honey patina. For versatility, a dark grey NATO offers perfect integration while maintaining sporty character. Avoid black satin leather, which clashes with the rose gold warmth: opt instead for chocolate brown or deep burgundy in artisanal quality leather.

Strap replacement involves using a dedicated tool to remove the spring bars from the case lugs. These bars hold the strap in place on either side of the watch: extract them carefully to avoid scratching the rose gold case. If you lack the proper tool, a professional watchmaker can complete the swap in minutes. I recommend having an expert handle the first replacement to master the correct technique without risk to your case.

Absolutely. Provided the strap is certified 20mm and constructed to reliable standards, an aftermarket strap does not compromise the watch or Longines warranty. In fact, it enables complete aesthetic personalisation: from alligator straps to NATO options, from vegetable-tanned leather to modern synthetics. The key is partnering with recognised manufacturers guaranteeing stainless steel bars and robust stitching. On milanostraps.it you'll find a curated selection of 20mm straps tested and ready to ship, with monogram personalisation and stitching thread options.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with moderate daily wear. Longevity depends on leather type (shell cordovan is exceptionally durable), usage frequency, sun and humidity exposure, and proper maintenance (avoid salt water and extreme heat). An aged alligator strap, regularly exposed to sunlight, develops a patina that becomes increasingly beautiful over time. I recommend keeping a backup strap to rotate wear and extend overall strap lifespan.
