Frequently asked questions

What is the lug width of the Unimatic Modello Cinque U5S-AN?

The lug width (ansa width) of the Modello Cinque U5S-AN is 22mm. This measurement allows you to use any standard strap designed for this width, offering extensive customisation options whilst maintaining full compatibility with the case.

Which strap is best suited for the Modello Cinque U5S-AN?

For a minimalist timepiece like the U5S-AN, we recommend vegetable-tanned leather straps in natural tones (burnt brown, cognac), which share the watch's design philosophy. Alternatively, a robust nylon NATO strap or a technical FKM option for daily wear.

How do I change the strap on my Unimatic Modello Cinque U5S-AN?

The strap is changed by removing the spring bars (small pins connecting the strap to the lugs). Using a spring bar tool or small screwdriver, press gently inward to release the pin, remove the old strap and insert the new one until you hear it click into place.

Can I use an aftermarket strap compatible with the Modello Cinque U5S-AN?

Yes, absolutely. Any strap with a 22mm lug width is 100% compatible with the Modello Cinque U5S-AN. No adapter is necessary: the strap will fit perfectly into the case lugs.

How long does a leather strap last on a watch like the Modello Cinque U5S-AN?

A vegetable-tanned leather strap typically lasts 3-5 years with daily wear, developing a characteristic patina. Longevity depends on humidity exposure, perspiration and maintenance. Store the strap in a dry environment and periodically clean it with a soft cloth to extend its lifespan.
