The Modello Due U2-H, seen from the bench

The Unimatic Modello Due U2-H is a 38.5mm stainless steel tool watch with a 22mm lug width, designed by Giovanni Moro and Simone Nunziato. Powered by the Sellita SW200-1 b automatic movement (26 jewels, 28,800 vph, ~38 hours power reserve), it features a high-contrast black dial, shaped hands, and a fixed caseback. Water-resistant to 10 atmospheres, the case combines satin-finished surfaces with sharp angles, mineral glass with anti-reflective coating, and screw-down crown for robust construction.

Frequently asked questions

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

The Modello Due U2-H features a lug width of 22 millimetres. This dimension is standard for the model and ensures compatibility with all 22mm straps in our collection. To measure your lug width correctly, place a calliper from the centre of one lug to the centre of the opposite lug, passing through the base of the case: the result should be exactly 22mm.

Which strap do you recommend for the Unimatic Modello Due U2-H?

For the Modello Due U2-H, we recommend a vegetable-tanned leather strap, such as our Heritage Collection in Honey Tobacco tonality. This choice enhances the brutalist and minimalist aesthetic of the watch, allowing the leather to develop a natural patina over time. Alternatively, a NATO strap in durable canvas or an alligator strap for a more formal upgrade.

How do I change the strap on the Unimatic Modello Due U2-H?

To change the strap, first remove the watch from your wrist. Using a spring bar tool or dedicated instrument, gently press the internal spring of the pin on the upper lug, extracting the pin from its housing. Repeat the procedure for the lower lug. Insert the pins of the new strap into the housings and verify they are fully seated. The operation takes just a few minutes and requires no specialised tools.

Are Milano Straps compatible with the Modello Due U2-H?

Yes, all 22mm straps in our collection are fully compatible with the Modello Due U2-H. We offer straps in vegetable-tanned leather, alligator, calf, shell cordovan, NATO canvas and FKM rubber, available in numerous tonalities. Each strap is handcrafted and customisable according to your preferences for length, buckle and finishing.

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

A high-quality artisanal leather strap, such as our vegetable-tanned options, typically lasts 3–5 years with daily wear, provided it receives proper care. Regular exposure to water, perspiration and sunlight accelerates wear. To extend longevity, we recommend cleaning the leather periodically with a damp cloth and applying a natural leather protectant every 6–12 months.
