Strap for Modello Uno U1-D

The lug width of the Unimatic Modello Uno U1-D is 22 mm. This measurement refers to the distance between the two lugs where the strap attaches to the case. To verify compatibility with an aftermarket strap, measure the internal gap between the lugs.

For the Modello Uno U1-D, we recommend straps in vegetable-tanned Tuscan leather or alligator, which complement the minimalist aesthetic of the case. If you prefer versatility, a nylon NATO or vulcanized rubber strap offers compelling stylistic contrast. Your choice should reflect your lifestyle and frequency of use.

Strap replacement is performed using the lug pins (spring bars). Use a dedicated tool to depress the internal spring, then pull the pin towards you whilst keeping the lever in position. Once the old strap is freed, align the new strap and reinsert the pin until the spring clicks into place. This procedure takes only minutes and requires no specialised tools.

Yes, any strap with a 22 mm lug width is compatible with the Modello Uno U1-D. However, we recommend verifying the strap thickness: the Modello Uno U1-D works best with straps between 3 and 4 mm thick, which ensure smooth transition between case and wrist without play or excessive rigidity.

A quality leather strap, with regular maintenance, lasts 3–5 years under daily wear. Longevity depends on tanning method: vegetable-tanned leather develops a natural patina and tends to outlast chrome-tanned calf leather. Frequent exposure to water, perspiration, and UV rays accelerates ageing. To extend strap life, rotate between multiple straps and condition the leather every 6–12 months.
