The Pilot Watches 861945, seen from the bench

The Laco Pilot Watch 861945 is a 42mm stainless steel tool watch evolved from 1925 German aviation traditions. It features an ETA caliber 2824-2 automatic movement with 38-hour power reserve, a black dial with luminous Arabic numerals, cathedral hands following DIN 8305 standard, and a date window at 3 o'clock. Water-resistant to 300 meters, this instrument watch requires a 22mm lug width strap matched to its proportions.

Frequently asked questions

What is the lug width of the Laco Pilot Watches 861945?

The lug width of the Laco 861945 is 22mm. This measurement represents the distance between the two attachment points on the case where the strap connects. To verify your measurement accurately, remove the original strap and measure with a calliper the distance between the lug shoulders. Any 22mm aftermarket strap will be fully compatible with this model.

Which strap is the best for the Laco Pilot Watches 861945?

The choice depends on usage and desired aesthetics. A black vegetable-tanned leather strap creates perfect harmony with the carbon dial, enhancing the tool watch identity. NATO straps in high-density weave represent the historical choice for aviators, guaranteeing stability and narrative appeal. For marine or tactical environments, FKM rubber offers superior resistance and grip. We recommend assessing your primary use context: formal requires leather, tactical favours NATO, sport-water welcomes rubber.

How do you change the strap on the Laco Pilot Watches 861945?

Remove the watch from your wrist and place it on a stable surface. Locate the spring bars securing the strap to the lugs (one on each side). Using a spring bar tool or small flat screwdriver, apply gentle pressure towards the watch case to compress the internal spring, then carefully extract the bar from its seat. Repeat on the opposite side. The original strap now separates from the case. Align the new strap's lug, then reinsert the spring bar whilst compressing the spring until you hear a click. Verify the strap is secure before wearing the watch.

Are aftermarket straps compatible with the Laco Pilot Watches 861945?

Yes, absolutely. Any 22mm strap is compatible with the 861945, provided the lug attachments align with the case proportions. Quality artisanal straps offer considerably broader material and colour choices than the original. We advise against lower-quality straps, which may present imprecise manufacturing tolerances, compromising stability on the lugs. Rely upon manufacturers specialising in aviation or instrument watches.

What is the lifespan of a leather strap for the Laco Pilot Watches 861945?

A quality vegetable-tanned leather strap, with regular maintenance, can last between 5 and 8 years. Longevity depends on intensity of use, exposure to moisture, sunlight and periodic conditioning with protective oils. An aviation watch like the 861945 is often used in demanding conditions—perspiration exposure, temperature fluctuations—that accelerate leather ageing. We recommend alternating with a second strap (NATO or rubber) to extend the life of both, and applying conditioner balm every 12 months.
