Frequently asked questions

What is the lug width of the Unimatic Modello Uno UC1?

The Modello Uno features a 22mm lug width, a carefully considered dimension that echoes Italian classical watchmaking proportions. Always measure between the inner extremities of the lugs before purchasing an aftermarket strap.

What strap do you recommend for the Unimatic UC1?

We primarily recommend vegetable-tanned Tuscan leather, which engages naturally with the minimalist satinised case. The leather develops authentic patina parallel to the steel's oxidation. Versatile alternative: cotton or linen NATO straps for casual wear, or alligator for discrete elegance.

How do you change the strap on a Unimatic watch?

The Modello Uno features standard lugs with straight spring bar passages. Use a spring bar tool to gently remove the spring bars securing the original strap. Align the new strap's holes with the lugs and reinsert the spring bars—they are retractable and will click into position with gentle pressure. Avoid forcing, which may scratch the steel lugs.

Are Milano Straps' straps compatible with the UC1?

All our 22mm straps are certified compatible with the Modello Uno. We calibrate padding and thickness to guarantee perfect ansa fit without visual play. When ordering online, compatibility is mathematical—mention the exact model in order notes for final verification before dispatch.

How long does a leather strap last on a daily-worn watch?

A quality Tuscan leather strap with vegetable tanning withstands 3-5 years of moderate daily use. Wrist friction, perspiration and sunlight accelerate natural ageing. We recommend rotating with at least two straps to extend each strap's lifespan. Treatment with natural wax every 6-8 months preserves leather flexibility and delays failure phenomena.
