Frequently asked questions

What is the lug width of the Laco Chronographs 861586?

The Laco Chronographs 861586 features a 22mm lug width, a standard specification for chronographs of this size (44mm case diameter). Lug width is measured as the linear distance between the two spring bar holes on the case and determines compatibility with all aftermarket straps.

Which strap is best suited for the Laco 861586?

For this aeronautically-inspired chronograph, we recommend a vegetable-tanned alligator leather strap, which enhances the watch's functional character without contradicting its military heritage. Alternatively, a Cordura canvas NATO strap offers tactical robustness, or natural vulcanized rubber for a waterproof, durable option.

How do I change the strap on my Laco Chronographs 861586?

Obtain a spring bar tool (extractor tool). Insert the bifurcated tip into the lateral holes of the lug, apply gentle downward pressure to compress the internal spring, then remove the strap. Align the new strap with the lug slots, reinsert the spring bars, and verify secure engagement with a light pull.

Can I use an aftermarket strap on this watch?

Yes, any strap with a 22mm lug width is compatible. Milano Straps offers a complete selection of 22mm straps in hand-perforated leather, alligator, shell cordovan, canvas NATO, and natural rubber, all ready to ship and customizable to your preferences.

How long does a leather strap last on a chronograph like this one?

A quality leather strap (alligator, calf, shell cordovan) with vegetable tanning typically lasts 3-5 years with daily wear, varying according to climate, humidity, and frequency of use. The patina that develops is a sign of authenticity. Natural vulcanized rubber lasts 5-7 years without patina, whilst canvas NATO exceeds 10 years.
