The Navy Watches 862104, seen from the bench

The Laco Navy Watch Cuxhaven model 862104 is a 42.5mm stainless steel watch evolved from German military chronometers designed in 1925 for the Kriegsmarine. It features an ETA Caliber 6498-1 automatic movement with 42 hours power reserve, a monochromatic dial with applied indices and Arabic numerals following Flieger standards, and a screw-down crown for secure grip. The 22mm lug width accommodates standard NATO straps and aftermarket leather options while maintaining visual balance with the case diameter.

Frequently asked questions

What is the lug width of the Laco Navy Watches 862104?

The lug width of the Laco 862104 is 22mm, measured between the internal lugs of the case. This dimension is the standard for mid-size German watchmaking tradition and ensures compatibility with a wide range of artisan and standard watch straps.

Which strap would you recommend for the Laco Navy Watches 862104?

For the 862104, we recommend three primary options: a vegetable-tanned leather in brown or burgundy tones for everyday elegance; a NATO strap in polyamide navy blue for historical authenticity; alligator in sand or taupe for business contexts. The choice depends on intended use and personal style.

How do I change the strap on my Laco 862104?

Strap change requires two tools: a spring bar tool (small extractor) and gentle movement. Position the extractor under the internal spring of the lug, compress slightly, slide out the old strap, and insert the new one aligning its ends with the case lugs. The operation takes 2-3 minutes per side.

Are aftermarket straps compatible with the Laco Navy Watches 862104?

Yes, completely. Since the 22mm lug width is a widely adopted standard, any strap measuring 22mm will install correctly on the 862104. We recommend verifying strap thickness against the case's lateral guides to ensure a secure fit without lateral movement.

How long does a leather strap last on a watch like the Laco 862104?

A quality leather strap with vegetable tanning typically lasts 3-5 years with daily wear, depending on environmental humidity and maintenance. Alligator or shell cordovan can reach 7-10 years. Replacement is recommended when the strap begins showing structural cracks near the lugs.
