Frequently asked questions

What is the lug width of the Unimatic Modello Uno U1-H?

The lug width of the Unimatic Modello Uno U1-H is 22mm. This dimension is standard for sports and professional timepieces and allows you to wear a wide variety of leather, rubber, fabric, and metal straps whilst maintaining aesthetic coherence with the 41.50mm case.

Which strap pairs best with the Modello Uno U1-H?

The ideal strap depends on your intended use and personal taste. To maximise the minimalist identity of the U1-H, we recommend either a matte black alligator with curved lugs or vegetable-tanned veal in matte black satin finish. These noble materials dialogue with the black satin dial and develop natural patina over time, amplifying the aesthetic of the construction.

How do I change the strap on the Unimatic U1-H?

The Modello Uno employs standard spring bars. To change the strap, use a dedicated spring bar tool to compress the internal spring, lift the pin from its seat, and remove it. Align the new strap with the lugs and reinsert the pin until you hear a click. We recommend working on a soft surface to avoid scratching the case.

Are there compatible aftermarket straps available for the 22mm lug width of the U1-H?

Yes, absolutely. The 22mm lug width is standard in the premium watch accessories market. Milano Straps offers a dedicated collection of 22mm straps in alligator, vegetable-tanned veal, shell cordovan, technical rubber, and NATO, all selected and tested for optimal proportions and thickness with the U1-H case.

What is the typical lifespan of a leather strap for the Modello Uno U1-H?

A quality leather strap (alligator or vegetable-tanned veal) offers a durability of 18–36 months with daily wear, depending on frequency of use and care. Vegetable-tanned leather develops natural patina that extends its visual appeal, whilst FKM rubber resists longer in humid environments. Avoid prolonged exposure to fresh and salt water to slow wear at the stress point.
