Piaget Square 18k Diamond Onyx 1970s

Launched in 1957, the 9P caliber was groundbreaking for 2 reasons: standing at 2mm, it was the thinnest manual-wound movement ever made for wristwatches, and its 20.5mm 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 black Onyx dial with four diamonds at twelve, three, six and nine o'clock.
