Launched in 1957, the 9P caliber was groundbreaking for 2 reasons: standing at 2 mm, it was the thinnest manual-wound movement ever made for wristwatches, and its 20.5 mm diameter was much larger than the standard, therefore allowing for larger cases.

Its slimness was not only a technical accomplishment, it also allowed the manufacture to fit dials made of hard stones while retaining a thin profile, like this flawless 18k Piaget with gold colored dial.
