Laco
Pilot Watches 861971— lug 20mm

The Laco 861971 is equipped with a 20-millimetre lug width. This measurement is crucial for determining aftermarket strap compatibility. To verify, measure the internal space between the two lugs on the case: it should measure exactly 20mm.

This depends on your intended use. For sartorial elegance, we recommend alligator or vegetable-tanned calf leather in dark brown. For sporty wear, a NATO strap in Cordura canvas maintains the watch's aviator spirit. For daily durability, vegetable-tanned calf with natural patina balances aesthetics and practicality.

The Laco 861971 features a standard lug system. Obtain a spring bar tool (inexpensive), insert it laterally under the lug, and gently press upward to release the spring bar. Slide out the old strap and insert the new one using the same method. The operation is completely reversible and poses no risk to the case.

Yes, absolutely. The 861971 features standard 20mm lugs, compatible with any artisanal strap of that measurement. Avoid excessively rigid straps or those with excessive thickness, which could strain the lugs. Milanostraps' 20mm straps are tested for this compatibility.

A high-quality strap with vegetable tanning typically lasts 3–5 years with daily wear, considering exposure to perspiration, humidity, and natural fibre degradation. Longevity increases if you rotate it with other straps, allowing the leather to dry completely. Periodic maintenance—gentle cleaning with a damp cloth—extends the strap's lifespan.
