FAQ
What is the exact lug width of the Laco Vintage 861784?
The lug width of the Laco Vintage 861784 is precisely 18mm. This measurement is taken from the inner shoulder to the inner shoulder of the case lugs where the strap attaches. It is essential to verify that any aftermarket strap is specified for exactly 18mm compatibility; straps measured at 16mm or 20mm are not compatible with this model.
Which strap do you recommend for the Laco Vintage 861784?
For a Flieger of this calibre, we recommend vegetable-tanned calf leather in dark brown or medium cognac tones. These materials develop natural patina and respect the historical aesthetic. Alternatively, a NATO strap in black or dark blue is ideal for functional wear, whilst vulcanised rubber in black offers contemporary minimalism without stylistic compromise.
How do you change the strap on a watch of this type?
Strap replacement requires a spring bar removal tool. Insert the tool into the narrow gap between the case lug and the strap terminal, apply gentle lateral pressure to disengage the internal spring bar, and extract the strap. Repeat on the opposite lug. Align the new strap's holes with the case lugs and press firmly until the spring bar engages. Avoid hammers or excessive force.
Are aftermarket straps available in the 18mm size?
Yes, Milano Straps offers a dedicated collection of 18mm-compatible straps. Options include Italian calf leather, reinforced cotton NATO, alligator, and vulcanised rubber. All straps have been mechanically tested for compatibility with Laco and similar brands. The collection is available for online order with customisation options including buckle style, keeper placement, and stitch colour.
What is the typical lifespan of a leather strap for this watch?
A vegetable-tanned quality calf strap typically lasts 3–5 years with daily wear, depending on humidity exposure, frequency of use, and maintenance. The leather will develop natural patina and micro-scratches that enhance character. After 5–7 years, the material may weaken at connection points. NATO cotton straps offer similar longevity but are easier to replace. Rubber maintains structural integrity for 2–4 years before hardening.
