Strap for UR-105M

No. The bracelet is integrated into the case and the lugs are asymmetrical, proprietary. A standard strap will not fit. To have a strap on this watch, I craft one by hand at my <a href="/pages/casati-booking">Atelier Casati Milano</a>, shaping the attachments directly to the case geometry.

I work by appointment only at my <a href="/pages/casati-booking">Atelier Casati Milano</a>. I take measurements and tracings directly from the case, studying how the lugs dialogue with the leather. Each strap is constructed specifically for that particular case — there is no standard template.

I favour Mississippi alligator. This watch is sporty and contemporary, and its futuristic geometry deserves a leather that ages with character, developing patina and slight rigidity over time. Alligator offers solidity without weighing down the asymmetry of the case.

With daily wear and minimal care — wipe it with a damp cloth, avoid prolonged direct sunlight — a strap wears beautifully for 8 to 10 years. The leather will change colour, it will gain patina. This is not deterioration; it is history written on the surface.

Titanium aluminium nitride protects the titanium from oxidation and colours it gold. It is not a fragile coating — it is integrated into the material itself. Urwerk's choice reflects the same principle that guides my craft: every constructive detail has a reason, a function beyond aesthetics.
