The Patek Philippe Reference 3445 Monodate is launched in 1960-1961 and remained in production until the early-1980s. The majority in yellow gold, more rarely in rose gold, even more rarely in white gold or platinum. The last watches produced, circa 1980, bear a sapphire screwed case-back (Ref. 3445-100 by Les Ateliers Réunis, Geneva; key No. 28). Around 3 000 examples were produced, some with integrated bracelet (Ref. 3445-6, etc.).
