These are two specially colored, limited edition 1966 models that Girard-Perrgaux is making to celebrate the 150th anniversary of Paris-based Le Printemps. Le Printemps is a famous department store and tourist draw on Boulevard Haussmann, and they have a variety of “special products” created this year for their anniversary.
As for the 1966’s seen here, we have two models: the larger model is sized at 38mm, in rose gold. The smaller is a 30mm ladies model, also in rose gold though with the addition of a nice single row diamond bezel and hour markers. The movement is GP’s GP03300-00030 automatic mechanical for the men’s model, the GP03200-0005 for the ladies. The dial is an intense brownish-red with radiant sunray finish. Very nice!
