Strap for Pilot Watch Original Friedrichshafen Stainless Steel / Black

The lug width of the Laco 861753 is 22mm. This measurement is the distance between the two lateral lugs where the strap attaches to the case. When purchasing a replacement strap, it must be exactly 22mm compatible to ensure a precise fit without gaps or misalignment.

For the Laco 861753, we recommend three primary options: alligator leather with vegetable tanning (brown or black) for elegance and natural patina development over time; black or brown aniline calf leather for minimalism and aesthetic coherence with the watch's instrumental philosophy; NATO strap in grey or black canvas to emphasise the model's military and aviation heritage. Your choice depends on intended use: formal, daily wear, or casual-sporty applications.

Locate the two lateral lugs protruding from the case. Use a fine spring bar tool to gently lift the small internal metal ring of the lug, thus freeing the strap. Avoid forcing: gentle and precise movement is sufficient. Once the first lug is released, withdraw the strap. Repeat for the opposite side. To install your new strap, insert the lug first on one side, then the other, ensuring the internal ring is correctly positioned and seated.

Yes, the Laco 861753 is fully compatible with any aftermarket strap with a 22mm lug width. Whether leather, NATO, rubber, or specialist materials, simply verify the width is exactly 22mm. However, we recommend selecting straps manufactured with precision tolerances to ensure optimal fit and mechanical longevity without compromise.

A naturally vegetable-tanned leather strap can last between 5 and 12 years, depending on frequency of use, moisture exposure, and maintenance practices. A strap worn daily in humid conditions (showers, marine environments) will have a shorter lifespan than one used in dry, protected contexts. Regular maintenance—gentle cleaning and protection with natural oils—significantly extends strap longevity.
