Strap for Modello Uno U1-MY2 Mihara Yasuhiro

The lug width (misura ansa) of the Modello Uno U1-MY2 is 22 millimetres. This dimension represents the space between the two case lugs where the strap is attached. To verify compatibility of an aftermarket strap, measure the distance between the inner edges of the lugs using a digital calliper, excluding the case width itself.

The Modello Uno U1-MY2 benefits particularly from vegetable-tanned leather straps in dark brown tones, which create elegant contrast against the stainless steel case. A second excellent choice is a NATO strap in canvas, which amplifies the tool watch heritage of the timepiece. For a monolithic contemporary aesthetic, black in calf leather or professional-grade rubber represents the most visually cohesive solution.

Strap replacement requires a spring bar removal tool or a small flat-head screwdriver. Gently insert the tool under the small metal spring (spring bar) connecting the strap to the lug, pressing inward to release the end. Remove the old strap from one side, then repeat the operation on the other lug. Position the new strap in the slots and reinsert the spring bar until it clicks into place.

All straps with an exact 22mm lug width are compatible with the U1-MY2. Milano Straps offers a dedicated collection of 22mm straps in leather, alligator, vegetable-tanned calf, canvas NATO, and professional-grade rubber, carefully selected to harmonise aesthetically with the minimalist design of this Italian tool watch.

The lifespan of a leather strap depends on frequency of use, climate conditions, and material quality. An excellent vegetable-tanned leather strap, worn daily, maintains structural integrity for 4–6 years before requiring replacement. With vegetable tanning, leather develops a natural patina that enhances aesthetics over time. Proper maintenance—drying after prolonged moisture exposure, occasional conditioning—significantly extends longevity.
