Strap for Pilot Watch Basic Aachen Stainless Steel / Black

The lug width of the Laco Pilot Watches 861990 is 18mm. This specific dimension ensures the strap fits perfectly onto the attachment lugs without lateral play. To verify compatibility, measure the distance between the two lugs with a digital calliper: it must be exactly 18.00mm.

We recommend a strap in alligator or vegetable-tanned calf leather for the 861990: these materials enhance the austere and functional character of the German pilot watch. A NATO strap in canvas is excellent for informal and outdoor contexts. For more robust daily use, an FKM rubber strap guarantees durability and easy cleaning whilst maintaining the military profile.

Changing the strap requires a specific tool: the spring bar tool. Remove the metal ring at the base of the lug with care, extract the spring, and insert the new strap. Work carefully to avoid scratching the case. If you prefer, you can consult a specialist workshop or contact Casati Milano for personalised service.

Yes, any strap with an 18mm lug width is compatible with the 861990. Verify that the width is exact (18mm) and that the total length is sufficient for your wrist, considering the possibility of adjusting the length by punching if necessary.

A quality leather strap, vegetable-tanned, has an average lifespan of 5-7 years with daily wear. Longevity depends on sun exposure, humidity and frequency of use. With proper maintenance (periodic cleaning and protective treatments), it is possible to extend the strap's life to 10 years. Rubber or NATO canvas straps have superior durability, up to 10-15 years.
