Strap for Pilot Watch Original Friedrichshafen Erbstück Stainless Steel / Black

The lug width of the Laco Pilot Watches 861934 is 22 millimetres. This dimension is the standard for mid-to-large instrument watches and allows compatibility with a wide range of artisanal straps. To verify the measurement, use a digital calliper to measure from hole to hole of the lug, perpendicular to the case shoulder.

The choice depends on intended use: for tactical contexts and humid environments, premium NATO in black or moss green ensure durability and grip even with gloves. For formal elegance, shell cordovan leather with vegetable tanning in light brown develops extraordinary patina. For tropical climates, vulcanised rubber in anthracite grey offers hygiene and thermal stability. We recommend evaluating according to your lifestyle: pilot? Military? Sartorial?

Remove the watch from your wrist. Using a spring bar tool, press the trigger on the internal torsion spring of the lug, then slide the bar laterally. The spring releases and you can extract the old strap. Insert the new strap by aligning the holes with the lugs, then slide the bar until you hear the spring click into place. Check that the strap is firmly secured before wearing the watch.

Yes, any strap with an exact 22mm lug width is compatible. We recommend Italian artisanal leather straps, premium NATO textile, and vulcanised rubber. Avoid straps of approximate width (22.5mm or 21.5mm), as they cause lateral play and accelerated wear of the lug pads. At milanostraps.it you'll find 22mm straps in leather, NATO and rubber ready for shipment.

A quality leather strap with vegetable tanning lasts on average 3-5 years with daily use, with variables related to climate (humidity accelerates ageing) and lifestyle. The leather softens progressively and develops natural patina. Accelerated deterioration occurs if exposed to constant rain without maintenance: we recommend periodic treatment with natural wax. Shell cordovan lasts 5-8 years due to fibre density. NATO and rubber do not deteriorate aesthetically but maintain unlimited use.
