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
Certina DS PH200M 40 mm Slate Ceramic sits within Certina's DS PH200M line, introduced in 2010. It carries the house codes established since 1888 — ceramic case, slate grey dial and automatic, 38-hour reserve — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

Brand history
Certina has spent more than 138 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's DS Action, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Adolf & Alfred Kurth established Certina in 1888, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Certina calibre produced today.
