Patek Philippe, Ref. 3445 Monodate
This reference is launched in 1960-1961 and remained in production until the early-1980s.
It’s the first “simple” calendar wristwatch made by Patek Philippe.
The majority in yellow gold, more rarely in rose gold, even more rarely in white gold or in platinum. The cases by Antoine Gerlach, Geneva.
The last watches produced, circa 1980, bear a sapphire screwed case-back (Ref. 3445-100 by Les Ateliers Réunis, Geneva).
Around 3 000 examples were produced, some with integrated bracelet (Ref. 3445-6, etc.).
According to our research, only ten examples of the Ref. 3445 in platinum are known to have appeared on the open market, three of these have diamond-set dials.
