Frequently asked questions

What is the lug width of the Unimatic Modello Due U2S-T-MP?

The U2S-T-MP features a 22-millimetre lug width, a standard measurement for mid-size watches. This dimension ensures compatibility with the majority of aftermarket leather and fabric straps, providing broad selection across material categories and finish options available from independent strap artisans.

Which strap is recommended for the Unimatic Modello Due U2S-T-MP?

Strap selection depends on intended use. For classical everyday wear, vegetable-tanned Tuscan leather develops natural patina over time. For sporty applications, nylon NATO straps offer functional durability. For aquatic environments, FKM rubber provides water resistance and stability. The titanium case harmonizes elegantly with neutral tones: dark brown, black, grey.

How do you change the strap on a Unimatic watch?

Strap replacement requires a spring bar tool—a simple X-shaped extractor. Insert the tool's tip into the small hole beneath the lug, gently compress the internal spring, then extract the strap pin. Repeat on the opposite side. Install the new strap by reversing the procedure, ensuring the spring bars seat fully in both lug holes.

Which aftermarket strap is compatible with the Unimatic Modello Due U2S-T-MP?

Any strap featuring 22-millimetre lug width is compatible. Verify that strap extremities are slightly rounded for fluid insertion into lug apertures. Avoid oversized strap thickness that could create friction during installation. Our leather and rubber straps are engineered for optimal tolerances and seamless fitting.

How long does a leather strap last before replacement is necessary?

A quality vegetable-tanned leather strap typically lasts 3-5 years with daily use, whilst developing aesthetic patina throughout its service life. Longevity depends on water exposure, perspiration, and maintenance protocols. Occasional leather balm application extends durability significantly. FKM rubber straps maintain structural integrity for 5-7 years, remaining unaffected by humidity and temperature fluctuations.
