Strap for Modello Uno KSA

The lug width of the Unimatic U1-KSA is 22mm. This measurement is critical for selecting compatible watch straps. Always measure from the outer edge to the outer edge of the lug shoulders to verify compatibility with aftermarket straps.

Given the military-industrial aesthetic of the Modello Uno, the ideal strap is vegetable-tanned leather, which develops natural patina over time and emphasises the watch's austere character. Robust NATO nylon and technical rubber options are also available for operational wear. The brushed stainless steel deployante completes the ensemble with precision.

Strap replacement requires a spring bar tool to extract the elastic pins from the lugs. Position the tool in the lateral grooves of the spring, apply controlled pressure toward the case centre, and the pin will spring out. Remove the old strap, align the new strap's holes with the lugs, and press until you feel the spring's locking click. The operation takes seconds and is fully reversible.

Yes, the Modello Uno U1-KSA accepts any strap with a 22mm lug width. Milano Straps artisanal straps are constructed specifically for this measurement and available in vegetable leather, calf skin, NATO nylon and cotton, and FKM rubber. All are ready to ship and customisable in colour and clasp type.

A vegetable-tanned leather strap, worn regularly (5-6 days per week), maintains structural integrity for 3–5 years before replacement is needed. Longevity depends on ambient humidity, cleaning frequency, and protective treatments applied. The patina that develops is characteristic of the material, not degradation; the strap ages gracefully and can be regenerated through light oiling.
