Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Urwerk UR-210 43 mm Slate 18k sits within Urwerk's UR-210 line, introduced in 1997. It carries the house codes established since 1997 — 18k yellow gold case, slate grey dial and in-house automatic — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.

Brand history
Urwerk has spent more than 29 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's UR-100, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Felix Baumgartner & Martin Frei established Urwerk in 1997, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Urwerk calibre produced today.
