Experience the craft of Jaeger-LeCoultre in the Polaris (ref. Q903818J), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 42 mm in diameter, with a thickness of 15.63 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel. The caseback is open, and the crystal is sapphire, delivering water resistance to 30000 meters. At a glance, the dial balances texture and clarity: a blue tone with gradient finish, framed by mixed hour markers, and stick hands. At its heart beats a proven engine: the 956AA caliber. First released in 2022. 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.
