Introducing Jaeger-LeCoultre Reverso (ref. 2578422), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 24.4 mm in diameter, with a thickness of 9.6 mm, defined by a rectangular silhouette. The caseback is double dial, 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 arabic numerals hour markers, and sword hands. At its heart beats a proven engine: the 968A 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.
