Strap for Pilot Watch Basic Sydney Stainless Steel / Black

The lug width of the Laco 861890 is 20mm. This measurement is essential when searching for compatible straps. It is not a widely common standard, so verifying compatibility before purchase is crucial. You can measure your watch's lug width using a calliper between the lugs of the case.

For the 861890, we recommend vegetable-tanned calf leather in warm brown or cognac tones. This material complements the stainless steel case beautifully and respects the German aviation heritage from which the watch originates. A robust NATO strap is the most authentic alternative for those wishing to emphasise the vintage character of the timepiece. An FKM rubber strap represents the modern sporty choice.

The strap is secured by two spring bars that pass through the case lugs. To remove it, use a dedicated spring bar tool to press the pins inward, allowing you to extract them. Once the pins are free, you can insert the new strap and reinsert the spring bars until they are fully seated. Care should be taken to avoid scratching the case during this process.

Yes, any strap with a 20mm lug width is compatible with the 861890. However, we recommend consulting specialist craftspeople who can offer superior-quality options. Milano Straps straps are handcrafted and available in various materials: leather, NATO, rubber. Always verify that the lug width is 20mm.

A high-quality leather strap with vegetable tanning typically lasts 3-5 years with regular use and routine maintenance. Longevity depends on humidity levels, frequency of wear, and care applied (periodic cleaning, protection from weather). Leather ages beautifully, developing patina and character, so visible wear is part of the material's inherent beauty.
