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

Panerai Luminor Due 37 mm Silvered 18k sits within Panerai's Luminor Due line, introduced in 2003. It carries the house codes established since 1860 — 18k rose gold case, silvered opaline dial and in-house manual-winding — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

  • The movement's bridges are decorated even where they will never be seen once the watch is cased.
  • The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
  • 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.
