Designer
Jörg Hysek
Jörg Hysek left Rolex and Seiko's European studios to build a design practice in Geneva, giving houses such as Vacheron Constantin, Breguet, Seiko and TAG Heuer their sculptural, architecture-led cases before founding his own brand, HD3.
Historical significance
Urwerk EMC 41 mm Slate Grade sits within Urwerk's EMC line, introduced in 2006. It carries the house codes established since 1997 — grade 5 titanium case, slate grey dial and satellite-hour automatic — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

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.
