Strap for Pilot Watch Original Kempten Stainless Steel / Black

The Laco 862093 features a lug width of 18mm. This measurement is critical when purchasing an aftermarket strap: the lugs represent the distance between the two steel pins that secure the strap to the case. An incorrectly sized strap (such as 16mm or 20mm) will not fit the lugs without structural modifications that would compromise the watch's integrity.

The choice depends on intended use and aesthetic preferences. For formal contexts, black alligator or shell cordovan create elegance without excess; vegetable-tanned calf leather offers softness and develops a fascinating patina over time; military-grade nylon NATO emphasises authentic pilot character; vulcanised rubber is ideal for aquatic or sports environments without visual compromise. The 18mm proportion maintains harmony with the 39mm case in all scenarios.

Position the watch on a soft surface (velvet cloth), with the dial facing downward. Locate the spring bars at the strap ends: using a dedicated spring bar removal tool (or gently with a sturdy needle), push from the opposite side to release the pin. Remove the old strap, lightly clean the lugs, position the new strap, and reinsert the spring bars until they click securely. Verify that the strap moves slightly once installed: excessive resistance indicates incorrect spring bar positioning.

Yes, absolutely. Quality straps manufactured to 18mm lug width fit without any issues. Reputable brands that produce straps for this specification guarantee complete compatibility. The critical detail is always verifying lug width (not case diameter) before purchase: 18mm is the determining factor. Customisable straps with robust fastening systems (passant loops, buckles, deployant clasps) enhance the ownership experience.

Lifespan depends on leather quality, usage habits, and maintenance. A high-quality calf or alligator strap typically lasts 3–5 years with moderate daily use (5–6 days per week), developing a beautiful patina over time. Exposure to sweat, moisture, and temperature fluctuations accelerates ageing; prolonged sunlight exposure fades colours. Occasionally applying leather-specific balms and keeping the strap dry significantly extends useful life. Shell cordovan and alligator, being denser leathers, last slightly longer than standard calf.
