Discover Jaquet Droz's precision with the Grande Seconde (ref. J006030240), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 43 mm in diameter, with a thickness of 12 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 matte finish, framed by mixed hour markers, and alpha hands. At its heart beats a proven engine: the 2663A.P 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.
