Discover Girard-Perregaux's precision with the 1966 (ref. 49523D11A171-CB6A), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 36 mm in diameter, with a thickness of 9.01 mm, defined by a round silhouette, paired with a gem-set bezel. The caseback is open, and the crystal is sapphire, delivering water resistance to 3000 meters. At a glance, the dial balances texture and clarity: a silver tone with guilloche finish, framed by mixed hour markers, and feuille hands. Among collectors, it is nicknamed "silver flinqué". At its heart beats a proven engine: the GP03300-0123 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.
