Strap for Modello Quattro U4S-HS Huckberry Earthform Collection

The lug width of the Unimatic Modello Quattro U4S-HS is 22 millimetres. This measurement is essential when selecting compatible aftermarket straps. Always ensure the strap slides smoothly through the spring bars without excessive play.

There is no single 'best' strap—choice depends on usage and personal style. For authentic artisanal character, a Tuscan leather with vegetable tanning in terracotta or aged cognac is recommended. For daily durability and versatility, a cotton-polyester NATO is practical and economical. For formal occasions, a brown or black alligator strap elevates the case proportions beautifully.

Strap replacement involves removing the spring bars using a dedicated extraction tool. Position the watch with lugs facing upwards, insert the extractor under the spring bar, apply gentle pressure and the bar releases easily. Insert the new strap, aligning it with the lugs, and close the bars. The procedure is reversible and damage-free if executed correctly.

Yes, absolutely. The Modello Quattro U4S-HS is designed to accommodate 22-millimetre aftermarket straps. Milano Straps maintains a carefully curated collection of leather, NATO and rubber straps in this width, guaranteed for mechanical compatibility and visual proportion with the 40-millimetre case.

Durability depends on tanning type and frequency of use. A vegetable-tanned Tuscan leather strap, with proper care (gentle cleaning, protection from prolonged rain, avoiding direct heat sources), lasts 5-7 years. Alligator or shell cordovan, being denser leathers, can reach 8-10 years. Natural leather wear is gradual and enhances aesthetic value (patina).
