Girard-Perregaux "Olimpico" chronograph [ca. late 1960s]

  • Movement: hand-wound Valjoux 72 diver/chronograph with column-wheel switching.
  • Case: stainless-steel, ~42mm Ø.
  • G-P offered a line of watches starting in the '60s thru the '90s, called "Olimpico" and ostensibly commemmorating the Olympic games, but never having any official affiliation or agreement. G-P ceased offering the line due to conflict with the International Olympic Committee over G-P's unlicensed use of the term "Olympic".
  • This particular piece is a less-common variant with a "sterile" dial sans "Olimpico" branding -- here are several examples with the more common Olimpico-signed dial.
  • This case design & movement combination was offered by a number of other brands -- here's an example from Wittnauer.
  • Case proportions and shape are very similar to the later Heuer Autavia chronographs.
