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
Panerai Radiomir 39 mm Meteorite 18k sits within Panerai's Radiomir line, introduced in 1981. It carries the house codes established since 1860 — 18k rose gold case, meteorite dial and in-house manual-winding — 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 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
Panerai has spent more than 166 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Luminor, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Giovanni Panerai established Panerai in 1860, working from Italy at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Panerai calibre produced today.
