Visiting casa de Rick this week, on it's way to the continent, is this vintage Zodiac chronograph.
Sadly named by some the 'Poor Man's Heuer', this Zodiac Ref. 73463 chronograph was, I believe, built in the Heuer factory, under contract to Zodiac. In fact, this watch has gained a Heuer signed crown somewhere in it's travels. Other then the crown, it appears to be in relatively original condition.
It is powered by a Valjoux 7334.
