Description

Nicknamed the “Curvtagon”, this rare Audemars Piguet reference 5418BA embodies a harmonious fusion of circular, rectangular, and cushion shapes, giving it a unique and distinctive presence. Its black matte dial recalls the rugged elegance of Rolex sports watches from the same era, while the bold “AP” logo at 12 o’clock adds a striking modernist touch.

At its heart beats the legendary Caliber 2121, one of the world’s thinnest self-winding movements with a date indication, measuring just 3.05 mm thick. This groundbreaking caliber also powered the iconic Royal Oak Ref. 5402 “Jumbo,” securing its place in horological history.

Paired with a refined teal alligator strap, this piece perfectly balances vintage audacity with timeless elegance. A true collector’s treasure, the 5418BA captures Audemars Piguet’s mastery of both design innovation and technical brilliance during the 1970s.
