Patek Philippe Calatrava ref. 3445
Launched in 1961 and in production until the early 1980s, the ref. 3445 was the first serially produced Patek Philippe self-winding, waterproof watch with a date.
The 35 mm watch was indeed powered by Patek's new and first serially produced automatic movement with a date, caliber 27-460.
Here's a random selection of several variants of this beautiful reference with a date window at 3 o'clock.
