Strap for Master Collection 34 Stainless Steel - Yellow Gold / Silver

The lug width of the Longines Master Collection L2.357.5.72.2 is precisely 18mm. This measurement is taken internally between the pins of the two lugs. It is essential to use watch straps specifically designed for 18mm, as different dimensions (20mm or 22mm) will not fit correctly into the watch's attachment points.

The best strap depends on your intended use. For formal elegance, crocodile leather in cognac tone or vegetable-tanned calf are excellent choices, as their natural texture pairs perfectly with the deep blue dial. For daily wear, aged brown leather offers practicality and develops characteristic patina over time. For summer, a grey anthracite rubber strap combines formality with comfort.

To change the strap, obtain a spring bar tool (a specialised instrument with two tips). Position the tips laterally on the pins connecting the strap to the lugs, apply inward pressure to release the pin, then remove the old strap. Insert the new 18mm strap by aligning the holes, then repeat the operation on the other lug. Verify that the pin is correctly inserted and that the strap is secure.

Absolutely. An aftermarket 18mm strap of the correct width is fully compatible with the Longines Master Collection L2.357.5.72.2. Ensure that the quality of stitching and leather is consistent with the watch's value. Custom artisanal straps also offer the possibility to adjust the total length and closure type (standard buckle, deployante, etc.).

The lifespan of a leather strap depends on frequency of use and material quality. A high-quality crocodile or shell cordovan strap lasts 5–7 years with moderate daily wear. A vegetable-tanned calf strap has a slightly shorter lifespan (3–5 years) due to lower leather density. Exposure to perspiration, water, and sunlight accelerates wear. Proper maintenance (regular cleaning, drying) significantly extends the strap's life.
