This vintage Audemars Piguet reference 5418BA from the 1970s is a captivating and unconventional expression of haute horology. Crafted in 18k yellow gold, its distinctive 32.5mm x 35mm octagonal case offers a bold, architectural presence on the wrist, with a remarkably slim 6mm profile.
Beneath its mineral crystal lies a sleek black dial, its geometric shape a subtle precursor to the iconic Royal Oak design. Powering this elegant timepiece is the legendary, ultra-thin automatic caliber 2121—a movement celebrated for its technical excellence. While presented on a black aftermarket strap, its provenance is elegantly confirmed by the accompanying vintage 18k white gold Audemars Piguet buckle. A rare and sophisticated find for the discerning collector.
