Strap for Pilot Watch Original Wien Erbstück Stainless Steel / Superluminova

The lug width of the Laco Pilot Watches 861944 is 20 millimetres. This measurement indicates the space between the terminal lugs of the case where the strap is attached. Always verify this dimension before purchasing an aftermarket strap to ensure absolute compatibility.

The ideal strap for the 861944 is leather with vegetable tanning (calf or alligator) in brown, cognac, or black tones. These materials complement the austere character of the fliegeruhr without overstatement. For intensive daily wear, a NATO polyamide strap is practical and reversible. For humid or marine environments, FKM rubber is resistant and durable.

Strap replacement is performed by removing the terminal pins using a dedicated tool (spring bar tool). Insert the flat blade of the tool into the lateral slots of the pins, press to release the internal spring, and extract the pin. Repeat on the other side. Insert the new strap by aligning the pins into the same holes and press until they click into place. If uncertain, consult a specialised watchmaker.

Yes, provided the strap is compatible with the 20 mm lug width. Verify that both ends of the strap are exactly 20 mm apart and that the pin slots are correctly dimensioned. A quality strap crafted by specialised artisans guarantees precise fitting and long-term durability.

Longevity depends on usage and tanning quality. A vegetable-tanned leather strap of good quality, subjected to moderate daily wear, typically lasts 3–5 years before replacement is required. Factors such as humidity, direct sunlight exposure, perspiration, and vibration accelerate wear. Periodic maintenance (cleaning, conditioning) extends strap life. Rubber or synthetic NATO straps last considerably longer in hostile environments.
