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
Yema Rallygraf 38 mm Slate Platinum sits within Yema's Rallygraf line, introduced in 2022. It carries the house codes established since 1948 — platinum 950 case, slate grey dial and quartz — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The movement's bridges are decorated even where they will never be seen once the watch is cased.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Yema has spent more than 78 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Superman, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Henry Louis Belmont established Yema in 1948, working from France at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Yema calibre produced today.
