Strap for Classics Berlin / Stainless Steel / White

The Laco Classics 861861 features an 18-millimetre lug width (ansa). This dimension is fully standardised and compatible with any strap from our 18mm collection. To verify compatibility with a strap you already own, remove the spring bars and measure the internal distance between the top and bottom lugs.

The Laco Classics 861861, given its German aviation heritage, pairs exceptionally well with three solutions. A vegetable-tanned alligator in brown or black amplifies the geometry of the steel case and the minimalist dial legibility. European calf leather with a wax finish in chocolate tones develops patina over time, ideal for formal wear. A NATO strap in ballistic canvas khaki immediately evokes its military origins whilst maintaining visual balance and operational practicality.

Strap replacement is a straightforward operation requiring a spring bar tool (readily available from any watch retailer). Position the watch on a soft surface, insert the tool into the lower spring bar slot, and lift the existing strap parallel to the case until the spring bar tension releases. Remove the bar with tweezers and repeat on the opposite side. Fit the new strap onto both bars, ensuring the internal springs click properly into place. Alternatively, contact Casati Milano for bespoke replacement by appointment.

Yes, any strap with an 18mm lug width is mechanically compatible with the Classics 861861. However, we recommend selecting straps of construction quality commensurate with the watch itself: artisanal calf in vegetable tanning, full-grain alligator leather, or military-weight textiles. Our atelier guarantees precise engineering tolerances and finishing standards that honour the original German design.

A high-quality artisanal leather strap typically lasts between 3 and 7 years, depending on frequency of wear, exposure to humidity, and preventative maintenance. Vegetable-tanned leather visibly ages, developing rich patina. To extend service life, avoid prolonged immersion in fresh water, apply a light conditioner every 6–8 months, and store the strap away from direct sunlight when the watch is not worn. A NATO or rubber strap lasts considerably longer—10–15 years—but does not develop the same aesthetic evolution.
