Frequently asked questions

What is the lug width of the Laco Pilot Watches 861951?

The Laco Pilot Watches 861951 features an 18mm lug width, calculated to maintain optimal proportions on a 45mm case. To verify your lug width, insert a credit card between the case and your current strap and measure the space in millimetres. An error in measurement would result in a strap incompatible with your watch's lugs.

What is the best strap for the Laco Pilot Watches 861951?

The ideal choice depends on intended usage. For formal contexts, we recommend an alligator strap with vegetable tanning, which develops a fascinating patina over time. For sports or tactical scenarios, a NATO strap in cordura grey or military green respects the Fliegeruhr spirit. If you frequently change straps, structured rubber offers consistent grip and zero maintenance.

How do I change the strap on the Laco 861951?

To remove the original strap, use a dedicated spring bar tool. Insert the tip into the lug slot and press gently to disengage. Never force with blunt objects—you risk scratching the case. Once the lugs are removed, insert them into the new strap, aligning the holes perfectly. Verify that the lugs are fully engaged before wearing the watch.

Which aftermarket strap is compatible with the Laco 861951?

Any strap with an 18mm lug width is compatible with the Laco 861951. Reputable brands offer straps in alligator leather, calf, ostrich skin, cordura NATO, and rubber. Always verify technical specifications before purchase. Milano Straps stocks a wide selection of 18mm straps ready for dispatch and customisable to your specifications.

How long does a leather strap last on a watch like the Laco 861951?

A premium leather strap (alligator, vegetable-tanned calf) has an average lifespan of 5-7 years of daily wear, assuming basic maintenance. Constant exposure to moisture, perspiration, and UV rays accelerates aging. A rubber strap lasts longer (8-10 years), whilst a NATO strap in cordura persists indefinitely. The natural patina that develops is an aesthetic quality, not a defect.
