Frequently asked questions

What is the exact lug width of the Laco Pilot Watches 861972?

The lug width of the Laco Pilot Watches 861972 is 20 millimetres. This standard dimension allows compatibility with a broad selection of artisanal straps, from exotic leathers to technical fabrics. To ensure compatibility with an aftermarket strap, verify that the lug width is certified at 20mm.

Which strap type pairs best with the Laco Pilot 861972?

Natural alligator in cognac or black tonalities represents the aesthetic pinnacle: the geometric scute grain dialogues with the applied Arabic numerals without visual competition. Alternatively, vegetable-tanned calf leather offers natural patina and tactile authenticity. For a declared avionic aesthetic, NATO in grey canvas or natural cotton is recommended.

How do you change the strap on a watch with 20mm lugs?

Use a springbar tool to lift the internal lug pins of the case. Insert the tip of the tool into the springbar release hole, pushing downward with steady pressure. The pin will retract, releasing the strap. Repeat on the opposite side. Insert the new strap by aligning the anchor holes with the lugs and release the springbar: you will hear a click indicating secure engagement.

Are aftermarket straps compatible with the Laco 861972?

Yes, provided the lug width is certified at 20mm. Artisanal aftermarket straps, manufactured by specialised ateliers such as Casati Milano, achieve quality standards superior to original equipment straps. Compatibility depends exclusively on width: 20mm guarantees universality across all standard lugs.

How long does a natural leather strap last on a wristwatch?

A vegetable-tanned calf leather strap, worn daily under normal conditions, maintains structural integrity for 5-7 years. Durability depends on ambient humidity, sun exposure, and maintenance frequency. Alligator leather, being more fibrous, tends to exceed 8 years of service. Strap replacement requires no technical case intervention: a change can be executed independently or through any watch service centre.
