Frequently asked questions

What is the lug width of the Unimatic Modello Cinque U5S-TA?

The lug width (misura ansa) of the Unimatic Modello Cinque U5S-TA is 22 millimetres. This dimension represents the distance between the two attachment points of the strap to the case. Verify compatibility by measuring the lugs perpendicular to the case with a digital calliper.

Which strap is recommended for the Unimatic U5S-TA?

For the U5S-TA, we recommend alligator straps with vegetable tanning to amplify the tool watch character, brush-finished calf leather in neutral tones to develop natural patina over time, or synthetic NATO for functional versatility and waterproofing. Your choice depends on lifestyle and context of use.

How do you change the strap on the Modello Cinque U5S-TA?

Remove the watch from your wrist. Using a spring bar tool, apply downward pressure on one end of the bar to release it from the lug. Insert the new strap into the lugs until you hear the bar click into position, repeating for the second side. Verify the strap is securely seated before wearing.

Are compatible aftermarket straps available for the U5S-TA?

Yes, Milano Straps offers a complete selection of artisanal 22mm straps, including options in calf leather, vegetable-tanned alligator, shell cordovan, synthetic NATO, and FKM rubber. All models are certified compatible and customisable according to aesthetic preferences.

How long does a natural leather strap last on a watch like the U5S-TA?

A premium-quality leather strap (alligator, calf, shell cordovan) develops a refined patina over time and resists 3–5 years under normal use conditions, reaching up to 7 years with periodic maintenance. Excessive humidity and prolonged contact with chlorinated water reduce longevity. We recommend alternating straps to extend overall durability.
