Patek Philippe Calatrava Ref. 3445 · 1960s · 35mm · White Gold A Calatrava 3445 in white gold with a factory diamond bezel. This reference marked an important step for Patek Philippe — the first time they produced an automatic watch with a date in series. A clean silver dial with everything in the right place, giving it a calm presence on the wrist. One that only gets better the more you wear it.
