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

Girard-Perregaux Casquette 36 mm Slate Sapphire sits within Girard-Perregaux's Casquette line, introduced in 1993. It carries the house codes established since 1791 — sapphire crystal case case, slate grey dial and in-house manual-winding — 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.

Brand history

Girard-Perregaux has spent more than 235 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Laureato, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.

Jean-François Bautte established Girard-Perregaux in 1791, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Girard-Perregaux calibre produced today.
