Audemars Piguet Octagon Blue Diamond 1970s

Audemars Piguet Octagonal Ellipse – Diamond Dial Ultra-Thin Elegance

This rare Audemars Piguet Octagonal Ellipse from the mid-1970s perfectly captures the bold yet refined design language of the era. Crafted in 18k yellow gold, the 31.5 mm case combines an octagonal geometry with elliptical proportions — a striking architectural design rarely seen in vintage AP watches.

The flawless blue sunburst dial is elevated by 12 factory diamond hour markers, complemented by elegant alpha hands and the classic AP signature.

Inside beats the ultra-thin Audemars Piguet Cal. 2003, a movement renowned for its slim profile and refined finishing. Paired with the beautifully integrated 18k yellow gold bracelet, the watch wears effortlessly — almost like a second skin.
