Strap for Modello Due U2-AG

The Unimatic Modello Due U2-AG features a lug width of 22 millimetres. This measurement is taken directly between the two attachment pins using a digital calliper. The 22mm lug width provides good versatility in sourcing aftermarket straps, allowing you to alternate between sports-oriented and formal solutions whilst maintaining aesthetic coherence.

The optimal strap choice depends on intended usage and desired aesthetic profile. For an elegant approach, we recommend vegetable-tanned calf leather that develops a natural patina over time. To preserve the tool-watch character, a premium cotton NATO strap is ideal. For outdoor activities, vulcanised rubber offers maximum stability and durability. All our 22mm straps are compatible with the Modello Due U2-AG and ready for immediate dispatch.

Strap replacement on the Modello Due U2-AG requires two basic tools: a spring bar tool and a clean work surface. Position the watch with the lug facing upward, insert the flat end of the tool into the small gap between the case and the pin, and apply gentle downward pressure to release the internal spring. Extract the pin by pushing the strap downward. Repeat on the opposite side. To install your new 22mm strap, insert the pin through the lug whilst applying lever pressure to the spring until the pin seats completely.

No, it is essential to verify that your aftermarket strap is specifically designed for 22mm lugs. A strap with incorrect lug width (for example 20mm or 24mm) will not install correctly and compromises both the aesthetics and functionality of the watch. All straps available on milanostraps.it are dimensioned for 22mm lug width, ensuring precise installation and complete stability.

A quality leather strap subjected to regular wear (5-6 days per week) typically lasts 3-5 years before showing significant signs of deterioration. This range varies depending on the tanning method used: vegetable-tanned leather develops a rich patina and character, whilst chemically-treated leather maintains a more static appearance. Natural wear is not a defect, but rather testimony to the bond between wearer and instrument. Vulcanised rubber straps, conversely, maintain their physical characteristics for 7-10 years without visible aesthetic changes.
