Strap for Modello Due U2-T-L Lorenzi

The lug width of the Unimatic Modello Due U2S-T-L is 22 millimetres. This measurement is taken between the two protruding pins on the case where the strap ends are inserted. Any strap compatible with 22mm lugs will fit this model perfectly.

For the U2S-T-L we recommend a vegetable-tanned leather strap, such as Tuscan Tobacco, which amplifies the industrial character of the titanium case and develops a golden patina over time. Alternatively, a nylon NATO strap emphasises the tool-watch aspect, whilst FKM rubber is ideal for marine environments. Your choice depends on primary use and wearing context.

To change the strap, obtain a spring bar removal tool. Insert the flat tip of the tool into the spaces beside the side pins, apply gentle pressure to release the internal spring mechanism, then extract the entire pin from the case. Repeat on the opposite side. Next, insert the new strap's pins into the same holes and press until you feel the click of engagement. Handle with care to avoid scratching the case.

Yes, all straps with 22mm lug width are compatible with the U2S-T-L. The aftermarket offers an extensive range of certified quality options: Italian leather, alligator, shell cordovan, NATO, and technical rubber. Always verify that the lug width is exactly 22 millimetres to avoid play or malfunction.

A vegetable-tanned leather strap of quality typically lasts 3-5 years under moderate daily wear conditions, developing a characteristic patina over time. Longevity depends on wearing frequency, climatic conditions and maintenance. Alligator or shell cordovan straps, being noble hides, can exceed 7-8 years. FKM rubber guarantees superior resistance in extreme environments, maintaining its properties for 5-6 years.
