Strap for Pilot Watch Original Dortmund Erbstück Stainless Steel / Black

The Laco Pilot Watches 861938 features a lug width of 22 millimetres. This dimension is the standard for this model and must match exactly the distance between the two spring bars on the watch case. Always verify this measurement before purchasing a replacement strap, as an incorrect lug width will not fit properly.

We recommend three primary options for the 861938: a black or dark brown alligator strap for formal elegance; a vegetable-tanned calf leather strap for natural patina development over time; or a NATO strap in grey or khaki fabric to maintain the historical avionic aesthetic. Choice depends on intended use: formal, daily wear, or sports. All must be 22mm lug width.

Remove the spring bars (small metal pins) from the lateral holes of the case using a dedicated spring bar tool or small flat lever. Pull outward to release the tension mechanism and extract the pin. Replace with your new strap, align the pins to the holes, and press until you hear a click confirming secure fixation. Ensure the lug width is exactly 22mm.

Yes, numerous aftermarket 22mm straps compatible with the 861938 are available on the market. Milano Straps offers a dedicated collection of straps in leather (alligator, calf), fabrics, and rubber, all specifically dimensioned for this lug width. All our straps guarantee complete compatibility and accommodate a deployante clasp if desired.

Leather strap durability depends on material type and usage patterns. A quality alligator strap, with moderate use, lasts 3-5 years. Vegetable-tanned calf leather, if properly maintained and protected from excessive moisture, can reach 4-6 years. Butyl rubber resists longer (5-7 years) under daily wear conditions. Periodic replacement is normal: the 22mm lug width of your 861938 allows for easy and rapid changes.
