Designer
Gérald Genta
Gérald Genta (1931–2011) trained as a goldsmith in Geneva and became the most influential watch designer of the 20th century. Working freelance, he sketched the Audemars Piguet Royal Oak overnight in 1970, followed by the Patek Philippe Nautilus, the IWC Ingenieur SL and the Bulgari Bulgari — defining the integrated-bracelet luxury sports watch as a category.
Historical significance
Certina DS Action 37 mm Silvered 18k sits within Certina's DS Action line, introduced in 2002. It carries the house codes established since 1888 — 18k yellow gold case, silvered opaline dial and automatic, 38-hour reserve — 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.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
