Strap for Master Collection Date 38.5 Stainless Steel / Silver

The lug width of the Longines Master Collection L2.628.4.78.6 is precisely 20 mm. This measurement represents the space between the spring bars that attach the strap to the case lugs. It is essential to respect this specification when selecting an aftermarket strap to ensure a secure and precise fit.

For the Master Collection L2.628.4.78.6, we recommend a brown or dark brown alligator strap, which complements the steel case tone and respects the watch's understated elegance. A vegetable-tanned calf leather is a valid alternative, developing patina over time. For daily wear and versatility, a NATO strap in cotton or silk in grey or navy blue offers practicality without aesthetic compromise.

To change the strap, position the watch with the case back facing upward. Use a small tool (springbar tool) to apply controlled pressure on the spring bars located at the case ends. Gently press one side to disengage the pin, then remove the strap. Proceed with care to avoid scratching the case. Insert the new strap by aligning the holes to the case lugs, then engage the spring bar until it locks securely.

Yes, you can use an aftermarket strap that is compatible with the 20 mm lug width. MilanoStraps offers handcrafted straps made from premium materials (alligator, calf leather, natural rubber, NATO fabric) specifically designed for this reference. All our straps guarantee manufacturing quality and durability equivalent to original Longines straps.

A quality leather strap (alligator or vegetable-tanned calf) with regular use has an average lifespan of 4-7 years, provided proper maintenance is observed. Frequent exposure to moisture, heat, or direct sunlight reduces longevity. MilanoStraps' handcrafted straps, made from carefully selected leather, are guaranteed for 18 months against manufacturing defects. Natural wear is part of the process of personalising your watch.
