Frequently asked questions

What is the lug width of the Laco Pilot Watches 861894?

The lug width of the Laco 861894 is 20mm. This standard allows for straps of identical width, eliminating gaps between case and strap. To verify correctly, position a calliper between the two upper suspension pins (lugs), perpendicular to the case's longitudinal axis. Inaccurate measurements are frequent without proper tools—we recommend contacting Atelier Casati Milano for free telephone verification.

Which strap is recommended for the 861894?

Selection depends on usage context. For formality: black alligator or caramel vegetable-tanned calf leather. For casual-sport: light grey or navy NATO. For humid environments: 4mm black satin rubber. Each material evolves over time—alligator maintains its natural grain invariantly, calf develops deeper patina, rubber resists without aesthetic degradation.

How do I change the strap on my Laco 861894?

The strap is secured via lugs: two metal pins protruding from the case, one on each side. Use a spring bar tool to compress the internal spring whilst extracting the pin from the lug seat. Insert the new strap by aligning the lug hole with the pin, then release pressure. The pin must click into position audibly. The operation takes 2-3 minutes for experienced hands; Atelier Casati Milano offers professional replacement service for those wishing to avoid risks.

What is the difference between an original and an aftermarket compatible strap?

Milanostraps aftermarket straps are constructed to identical OEM standards but with greater material and finish variety. Compatibility is guaranteed for 20mm lug width—the strap fastens via standard pins, requiring no case modification. Leather quality and texture vary: choose based on aesthetic preference and context. Longevity depends on maintenance, not manufacturing brand.

How long does a leather strap last on the 861894?

A high-quality leather strap with vegetable tanning resists 4-6 years of daily wear before requiring replacement. Longevity depends on: frequency of use (daily vs occasional), climate (humidity accelerates degradation), maintenance (apply protective balm every 6 months). Signs of ageing—scratches, colour shifts—are distinctive markers of authentic leather. Rubber straps last 8-10 years whilst maintaining grip and elasticity, showing no aesthetic alteration over time.
