Audemars Piguet Octagon Automatic Date 1970s

Audemars Piguet Octagon Automatic Date – 18k Yellow Gold – 1970s

Sculptural elegance meets mechanical finesse.

This 1970s Audemars Piguet dress watch stands out with its rare stepped decagonal case, crafted entirely in 18k yellow gold. The interplay of geometry and texture continues with the oval golden dial, featuring a subtle shimmering finish that catches the light with every movement.

Inside, the ultra-thin Caliber 2121/1 — developed in collaboration with Jaeger-LeCoultre — offers both mechanical prestige and slender comfort on the wrist. The movement is the same esteemed caliber used in the early Royal Oak models.

Completing the piece is an integrated 18k yellow gold braided bracelet, fluid and architectural, making this watch as much a piece of jewelry as a precision instrument.

With its sculptural form, rare case architecture, and storied movement, this AP is a refined yet bold statement for collectors and connoisseurs alike.
