Strap for Master Collection Date 36 Pink Gold

The Longines Master Collection L2.518.8.78.3 features a 19mm lug width. This measurement is the standard for this watch family and determines compatibility with aftermarket straps. To verify, measure the space between the two lugs on the case side: you will find exactly 19mm width.

For rose gold, we recommend alligator leather in dark tones (chocolate brown or black) for noble contrast, or shell cordovan which develops a deep patina over time. If you prefer visual breathing room, vegetable-tanned calf in pearl grey or beige subtly complements rose gold hues. For summer wear, black Tropic rubber offers practicality without thermal burden.

Use a spring bar tool to gently remove the elastic pins that secure the strap to the lugs. Insert the flat blade under the pin from the opposite lug side, lifting with gradual pressure: the pin will retract allowing extraction. Repeat on the other lug. For new strap installation, align the holes and insert the elastic pins until you hear a click. Avoid sudden impacts that could damage the pin.

Yes, provided the strap is 19mm lug width. Quality aftermarket straps maintain the same dimensions as Longines OEM straps, allowing complete interchangeability. Always verify the elastic pin diameter (typically 1.8-2.0mm) matches your watch. Specialist suppliers like milanostraps.it guarantee exact compatibility.

Leather strap lifespan varies by material and usage: alligator and shell cordovan maintain structure for 4-6 years with daily wear and proper care (avoid prolonged water exposure and direct sunlight). Vegetable-tanned calf has similar longevity but shows wear marks more visibly, which adds to patina appeal. Rubber remains functional for 5-8 years. To extend life, rotate straps and apply leather conditioner every 6-12 months.
