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
Patek Philippe Twenty~4 40 mm Silvered 18k sits within Patek Philippe's Twenty~4 line, introduced in 2022. It carries the house codes established since 1839 — 18k yellow gold case, silvered opaline dial and in-house manual-winding, hand-finished — 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 case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Patek Philippe has spent more than 187 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Nautilus, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Antoine Norbert de Patek & Adrien Philippe established Patek Philippe in 1839, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Patek Philippe calibre produced today.
