From Audemars Piguet, presenting the Royal Oak (ref. 77321ST.ZZ.D002CR.01), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 33 mm in diameter, with a thickness of 10.4 mm, defined by a other silhouette, paired with a gem-set bezel. The caseback is closed, and the crystal is sapphire, delivering water resistance to 5000 meters. At a glance, the dial balances texture and clarity: a black tone, framed by stick / dot hour markers, and feuille hands. At its heart beats a proven engine: the AP 2240 caliber. 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.
