FAQ

What is the lug width of the Laco Pilot Watches 861893?

The Laco 861893 features a lug width of 20 millimetres. This dimension is specific to Laco's oversized Pilot Watch collection and ensures visual and ergonomic balance with the 45-millimetre case diameter. Always measure the distance between the inner attachment holes to verify compatibility with any aftermarket strap.

Which strap do you recommend for the 861893?

We recommend dark brown alligator or vegetable-tanned calf leather for a classical, formal aesthetic. If versatility is your priority, a military grey NATO strap preserves the original aviatory heritage. For maritime environments or high-activity settings, synthetic rubber delivers durability and practicality without compromising the visual clarity of the two-tone dial.

How do you change the strap on a 20mm lug-width watch?

Remove the watch from your wrist. Using a spring bar tool, gently lever the elastic pin that secures the strap from inside the case. Once released, extract the old strap. Align the new strap's holes with the pins, then press the elastic pin into position until it clicks. Always verify that the strap is firmly secured before wearing.

Can I use an aftermarket 20mm strap with the 861893?

Yes, any strap with a 20mm lug width will be fully compatible with the Laco 861893. Simply ensure the measurement is correct (between 20mm and 20.5mm maximum) and that the strap's holes accommodate the case's spring bar pins. Italian artisanal straps offer superior craftsmanship and noble materials compared to industrial alternatives.

How long does a leather strap last on a Pilot Watch like the 861893?

Longevity depends on the tanning method and frequency of wear. A vegetable-tanned calf strap worn daily typically endures 3-5 years before the leather shows creasing and wear. Alligator, more resistant to tension stress, can exceed 6-8 years of regular use. A nylon NATO strap has virtually unlimited durability. Exposure to perspiration, moisture and direct sunlight accelerates ageing; storage in dry conditions significantly extends useful life.
