Frequently asked questions

What is the lug width of the Unimatic Modello Due U2-NC?

The Modello Due U2-NC features a lug width of exactly 22 millimetres. This measurement represents the distance between the horizontal lugs that attach the strap to the case. Verifying this specification is essential before purchasing an aftermarket strap to ensure perfect compatibility.

What type of strap pairs best with the Unimatic U2-NC?

The ideal strap depends on intended use. For maximum aesthetic coherence with the minimalist design, vegetable-tanned Tuscan leather imparts elegance without ornamentation. For versatility, a technical fabric NATO strap maintains the model's rationalist austerity. For sports or instrumental use, rubber is the most durable and resistant choice.

How do you change the strap on the Modello Due U2-NC?

The strap is secured to the case via lugs that thread onto the horizontal spring bars. To change it, use a spring bar tool to gently compress the internal spring, then extract the old strap. Insert the new strap's lugs into the slots and release the tool: the bar will snap into position. Ensure the lug width is precisely 22 millimetres.

Can I use an aftermarket strap on this watch?

Yes, absolutely. Any strap with a 22-millimetre lug width will be compatible with the U2-NC. Milano Straps offers a comprehensive range of vegetable-tanned leather, NATO, and rubber straps, all available in the 22mm size and customisable according to your aesthetic and functional preferences.

How long does a leather strap last on the Modello Due U2-NC?

A quality leather strap, such as vegetable-tanned Tuscan leather, typically lasts 3–5 years with regular use and proper maintenance. Longevity depends on exposure to water, perspiration, frequency of wear, and care applied. A well-maintained strap develops a fascinating patina that narrates the history of the watch's use.
