Frequently asked questions

What is the lug width of the Laco Navy Watches 862105?

The lug width of the Laco Navy Watches 862105 is 22 millimetres. This dimension is measured as the distance between the centres of the two lugs (pins) where the strap attaches to the case. It is essential to verify this measurement precisely using a digital calliper before ordering an aftermarket strap.

What is the best strap for the Laco Navy Watches 862105?

The optimal strap depends on intended use and personal aesthetic preference. For refined elegance we recommend alligator in vegetable tanning; for historical coherence a NATO in Ballistic canvas; for practicality a calf skin with fine grain finish. The ideal choice combines rigorous aesthetics and tactical functionality, maintaining visual balance with the 42.5mm diameter case.

How do I change the strap on the Laco Navy Watches 862105?

Strap replacement requires minimal tools: a spring bar tool (extractor). Position the watch on a soft surface, insert the tool's tip into the small recess housing the spring, press gently until the outer pin disengages with a click, withdraw the strap. Repeat on the opposite side. Insert the new strap by aligning the holes with the lugs and press firmly until you feel the spring mechanism lock.

Can I use aftermarket straps compatible with 22mm lugs?

Yes, absolutely. Any strap with 22mm lug width is compatible with the Laco 862105, provided the pins (spindles) share the same diameter, typically 1.5–1.8mm. Milano Straps offers a comprehensive selection of artisanal 22mm straps verified for this specification, crafted in premium leather and rubber.

What is the average lifespan of a leather strap on the Laco Navy Watches 862105?

A quality leather strap, subjected to moderate daily wear, typically lasts 3–5 years before replacement is necessary. Longevity depends on tanning method (vegetable tanning is more durable), leather thickness and frequency of use. Materials such as alligator and shell cordovan may endure 7–8 years or longer. Regular maintenance with specialised creams significantly extends functional life.
