Strap for Modello Uno GMT U1S-C-GMT-H Hodinkee

The lug width of the Unimatic Modello Uno UWK-U1S-C-GMT-H is 22 millimetres. This measurement represents the internal distance between the horizontal pins that secure the strap to the case. It is essential to verify that any aftermarket strap respects this exact dimension to ensure a stable fit free from lateral play. Milano Straps offers an extensive selection of 22mm straps specifically compatible with this model.

The ideal strap for the Modello Uno depends on intended use and aesthetic preference. Vegetable-tanned alligator amplifies the minimalist character of the titanium-carbon case, developing a unique patina over time. Italian smooth calf leather ensures elegance without compromise. For daily versatility, a ballistic nylon NATO offers practicality and the same aesthetic rigour. FKM rubber represents the technical choice, ideal for sporting or professional contexts. All these materials, in 22mm, are available at Milano Straps with Italian artisanal craftsmanship.

To change the strap, proceed as follows: 1) Remove the watch from your wrist. 2) Use a spring bar tool to compress the elastic pin from one side, creating sufficient space to extract the strap. 3) Remove the worn strap and position the new one by aligning the lugs with the pins. 4) Reinsert the pins by compressing them slightly until you hear an audible locking click. For greater security, we recommend having the operation performed by a professional watchmaker or at Atelier Casati Milano by appointment.

Milano Straps offers a specialised catalogue of artisanal straps in leather, NATO, and rubber, all crafted in Italy with attention to construction details and chromatic proportions.

It is possible to personalise your selection online or consult in-person at Atelier Casati Milano for a bespoke selection.

The lifespan of a leather strap depends on usage, climate, and material quality. Artisanal-grade alligator or calf leather in vegetable tanning, worn daily, maintains structural integrity for 3–5 years, whilst developing a patina that narrates its history of use. Exposure to perspiration, humidity, and UV radiation accelerates ageing. Thinner leather straps may require replacement sooner; greater thicknesses, such as those crafted by Milan artisans, prove more resilient. Regular maintenance—cleaning and occasional conditioning—significantly extends useful life. Milano Straps stocks replacement straps in 22mm ready to replace the previous one when necessary.
