Introducing Girard-Perregaux 1966 (ref. 49538-53-133-BK6A), 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 10.72 mm, defined by a round silhouette. 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 sunburst finish, framed by stick / dot hour markers, and feuille hands. At its heart beats a proven engine: the GP03300-0010 caliber. Introduced in 2012. 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.
