The UR-110 UR-210 Y, seen from the bench

The Urwerk UR-110 represents a contemporary timepiece that uses the patented satellite time indication system of the brand. It is powered by the automatic Caliber UR 9.01 with indication of hours, minutes and small seconds. The case features the asymmetric shapes characteristic of Urwerk's production.

Frequently asked questions

Can a strap be fitted to the Urwerk UR-110 UR-210 Y?

The lug attachment on the Urwerk UR-110 UR-210 Y does not follow standard straight-bar specifications; it is integrated into the case design. A standard commercial strap is not compatible, but a custom-made strap constructed directly onto the watch is possible. <a href="/pages/casati-booking">Casati Milano</a> specializes in this work, taking precise measurements at the atelier and crafting the strap using traditional methods.

How does the custom strap construction process work?

The process begins with an appointment at <a href="/pages/casati-booking">Casati Milano</a>, where exact measurements of the lugs and case geometry are recorded. The craftsman then creates the leather strap, calibrated to the specific structure of the watch. The result is a perfectly fitted accessory with no play, enhancing the coherence of the Urwerk's design intent.

Which leather is most suitable for the character of the Urwerk UR-110 UR-210 Y?

The sculptural and technical character of the Urwerk demands austere, structured leathers. Vegetable-tanned hides with natural patina, light aniline finishes, or smooth textures with artisanal edge painting are ideal. Neutral colours—black, dark brown, grey—emphasize the case geometry without competing with it. The choice should avoid ornamentation and prioritize function.

How long does a well-crafted artisanal strap last?

A strap made from quality leather with traditional artisanal techniques can last for years, developing a patina that reflects its history of use. Durability depends on the type of leather, daily care, and the quality of stitching and finishing details. <a href="/pages/casati-booking">Casati Milano</a> guarantees robust construction, designed to accompany the watch over the long term.

Why is the Urwerk UR-110 UR-210 Y considered a design masterpiece?

The 2014 Urwerk UR-110 combines mechanical innovation and design coherence. Its satellite complication transforms timekeeping into a kinetic experience, whilst the asymmetrical case in titanium and steel rejects all conventional symmetry. Every element—from the proprietary lugs to the external geometry—stems from a unified vision where form and function are indistinguishable.
