Experience the craft of Audemars Piguet in the Haute Joaillerie (ref. 79420BC.ZZ.9190BC.01), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in white gold and measuring 40 mm in diameter, with a thickness of 12.2 mm, defined by a other silhouette. The caseback is closed, and the crystal is sapphire. At a glance, the dial balances texture and clarity: a paved tone, framed by none hour markers, and dauphine hands. At its heart beats a proven engine: the AP 2601 caliber. Introduced in 2016. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
