Strap for Modello Uno U1-MP Mr Porter

The lug width of the Modello Uno U1-MP is 22mm. This dimension represents the internal space between the two lugs that attach the strap to the case. To verify compatibility with an aftermarket strap, measure this distance precisely using a digital calliper, perpendicular to the lug plane.

The Modello Uno U1-MP pairs elegantly with vegetable-tanned leather straps (cognac, black, burgundy), which preserve the watch's aesthetic minimalism. A regenerated textile NATO offers versatility and sustainability, whilst a vulcanised rubber strap represents the tactical choice for humid environments and sports. Dark alligator with hand-stitched seams adds austere elegance.

Use a spring bar tool or dedicated instrument to gently lift the spring bar pin on one side of the case. Remove the old strap, insert the new one by aligning the pins to the lugs, and verify locking by applying pressure until you hear a click. Ensure the pins are fully inserted into the lug holes before wearing the watch.

Vegetable tanning uses natural tannins for leather processing, creating a material that ages visibly by developing patina and personal character. Unlike chrome tanning (faster), vegetable tanning guarantees chromatic transparency, biodegradability, and softness that emerges over time. On a Modello Uno U1-MP, this process transforms the watch into an increasingly personal instrument.

A quality leather strap (vegetable-tanned) lasts 3-5 years with daily wear, extendable to 7-8 years with regular rotation between multiple straps. Durability depends on climate (humidity accelerates wear), wear frequency, and maintenance (drying after sweat, occasional conditioning). Vulcanised rubber, more resistant to moisture, can last 5-7 years without structural degradation.
