Strap for Elegant Collection Automatic 37 Stainless Steel / Black / Strap

The lug width of the Longines Elegant L4.810.4.57.2 is 19mm. This measurement is taken from the inner right shoulder to the inner left shoulder of the case, which is the space between the two holes where the strap attaches. A compatible strap must be exactly 19mm wide to ensure a precise fit and a harmonious appearance without visible gaps or overlaps.

For a timepiece of this elegance, a natural alligator leather in brown or black represents the ideal choice: the fine grain of the hide pairs perfectly with the sobriety of the dial. Alternatively, vegetable-tanned calf leather offers a fascinating natural patina development over time. For daily versatility, a NATO strap in premium canvas allows quick transitions between formal and casual settings whilst maintaining a refined aesthetic.

The change is accomplished by removing the 19mm lugs via the spring bars that support them. Using a dedicated spring bar removal tool (available for modest cost), apply controlled pressure on one of the two bars until the lug releases from one side of the case. Repeat the operation on the other bar, extract the lug, and insert the new strap by aligning it with the holes. No experience is required: the motion is straightforward, but demands care to avoid scratching the case.

Absolutely. Many quality aftermarket straps are perfectly compatible with this model, provided they respect the 19mm lug width and their lugs (or terminals) are engineered to accommodate your spring bars. Artisanal straps such as those offered on milanostraps.it guarantee premium materials and meticulous craftsmanship, often exceeding factory-supplied straps in quality.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 2–5 years with daily wear, depending on the tanning method and maintenance. A vegetable-tanned leather develops a distinguished patina over time, enhancing its aesthetic appeal. To extend longevity, avoid prolonged exposure to water, aggressive detergents, and heat sources. Periodic maintenance with products formulated for watch leather preserves elasticity and delays natural wear.
