Audemars Piguet 5420 | 18ct Yellow Gold | Calibre 2120 | Gerald Genta Design | 1970s
A rare and elegant example of the Audemars Piguet 5420, crafted in solid 18ct yellow gold and powered by the ultra-slim Calibre 2120 movement — the very same base calibre that would later define the legendary Royal Oak 5402.
This beautifully preserved tonneau-shaped dress watch is believed to have been designed in collaboration with Gerald Genta during the early 1970s, reflecting the refined design codes of that era. A piece that quietly shares lineage with one of the most iconic watches in horological history.

Our View
This Audemars Piguet Ref. 5420 is far more significant than it first appears. Designed in the same creative era and partnership as the Royal Oak, it houses the same celebrated Calibre 2120—one of the finest ultra-thin automatic movements ever made.
Its coin-edge case, champagne dial, and slender gold construction embody pure 1970s sophistication. Quietly confident, historically important, and beautifully balanced, this is a piece that bridges the worlds of classic dress and early sports design—an understated gem in Audemars Piguet’s lineage.
