Strap for Modello Uno x Eroica

The lug width of the Modello Uno U1-ER is 22mm. This dimension was deliberately selected by Unimatic to maintain precise aesthetic balance between the 40mm case diameter and the range of available straps. When purchasing aftermarket straps, always verify that the spring bars are exactly 22mm apart.

For the Modello Uno U1-ER, we recommend a strap in Tuscan leather with vegetable tanning in cognac, honey, or natural brown tones. This choice amplifies the authenticity message that characterises the watch. Valid alternatives include grey stone alligator for a more technical profile, or superior quality chromium-tanned calf for those seeking tactile softness and evolving patina over time.

The Modello Uno U1-ER features standard straight spring bars. Remove the bars using a dedicated spring bar tool, applying pressure to one side of the bar to make it snap inward. Once the old strap is extracted, align the new bars with the lugs and press until they click into position. The operation requires care to avoid scratching the case.

Yes, the Modello Uno U1-ER is fully compatible with 22mm aftermarket straps. We recommend choosing straps from reliable brands that guarantee construction quality and certified materials. Milano Straps offers a complete range of 22mm artisanal straps, tested for compatibility and durability on watches in this segment.

A superior quality leather strap (Tuscan, alligator, calf) typically lasts 3-5 years with daily use, provided it receives regular maintenance. Durability depends on exposure to humidity, sweat, prolonged sun exposure, and frequency of use. We recommend regularly checking spring bar integrity and applying a protective balm every 6-8 months to leather straps.
