Strap for Master Collection 38.5 Day Date Stainless Steel / Pink Gold / Silver-Diamond / Bracelet

The lug width (ansa width) of the Longines Master Collection L2.755.5.97.7 is 20 millimetres. This measurement is determined by the distance between the inner edges of the spring bars that attach the strap to the case. To verify it, use a digital caliper by inserting it into the spring bar seats: the value must be exactly 20mm to ensure the strap seats correctly without movement or binding.

For the L2.755.5.97.7 in pink gold and stainless steel, we recommend materials that dialogue with the case's dual-tone finish. Alligator in solid colours (dark blue, cognac brown, black) emphasises formality without competing with the rose gold. Shell cordovan treated with vegetable tanning offers compact grain that ages with nobility. In summer, a cotton canvas NATO or FKM rubber resistant to perspiration and chlorine maintains classical proportion. High-quality aniline calf develops a patina that documents the watch's history of wear.

Strap removal is accomplished by extracting the spring bars that connect the strap to the case. Use a dedicated tool or spring bar tool to gently press inward on one side of the bar, sliding it outward from the case. Repeat on the opposite side. Once the spring bar is extracted, the strap detaches. To install a new strap, align the attachment holes, reinsert the spring bar, and verify secure seating with an audible click.

Yes, the L2.755.5.97.7 is fully compatible with quality aftermarket straps, provided they respect the 20mm lug width. You may choose from artisan materials such as alligator, shell cordovan, aniline calf, or sporty options like NATO and rubber. Compatibility is guaranteed by the standardisation of spring bars; however, we recommend straps with 316L stainless steel fittings or gold-plated pins to maintain material coherence with the case.

A high-quality artisan leather strap (alligator, calf, shell cordovan) for the Longines Master Collection has an average lifespan of 4–7 years with daily use, depending on exposure to moisture, perspiration, and climate variation. Natural aniline leather typically displays visible patina after 12–18 months, a sign of natural ageing. To prolong lifespan, occasionally apply balms specific to watch leather, avoid prolonged immersion, and allow complete air-drying after perspiration contact. A well-maintained strap can reach 10 years with spring bar replacements.
