Frequently asked questions

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

The lug width of the Unimatic Modello Due U2S-T-HS is 22 millimetres. This dimension is standardised for the model and must be strictly observed when purchasing an aftermarket strap. Measurement is performed by inserting a tape measure through the lateral lug apertures of the case, from lug to lug, maintaining a perpendicular line to the dial.

What is the best strap for the Unimatic Modello Due?

There is no universally 'best' choice, as it depends on intended use and personal preference. For formal daily wear, vegetable-tanned leather is recommended, developing a natural patina in harmony with the titanium case. For tactical or coastal environments, recycled NATO straps offer practicality and sustainability. For technical diving, FKM rubber guarantees superior chemical resistance and wrist adhesion. The primary variable is contextual use.

How do you change the strap on the Unimatic Modello Due U2S-T-HS?

Strap replacement is performed by removing the lateral attachment pins connecting the strap to the case lugs. Use a spring bar tool to gently compress the internal springs of the pins, permitting extraction. Once removed, withdraw the previous strap, insert the new one (verifying 22mm compatibility) and reinsert the pins, ensuring they click fully into the lugs. The operation requires minutes and demands no watchmaking competence.

Is there an aftermarket strap compatible with this model?

Yes, any strap manufactured to the 22mm standard is compatible with the Modello Due U2S-T-HS. Milano Straps offers a complete range of artisanal 22mm straps, including vegetable-tanned leather, alligator, shell cordovan, sustainable NATO and FKM rubber. All are constructed to superior quality tolerances and available in multiple finishes, allowing you to adapt the instrument to different seasons and contexts.

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

The lifespan of a leather strap varies significantly based on tanning type, frequency of use and environmental conditions. A quality artisanal vegetable-tanned strap, worn daily, maintains structural integrity for 3–5 years before requiring replacement. Prolonged exposure to moisture, direct sunlight and fresh water accelerates ageing. However, the patina developed during this period represents the aesthetic value of the strap: unlike synthetic straps, natural leather straps improve visually over time before yielding, developing a unique colour signature.
