From Zenith, presenting the Defy Extreme (ref. 97.9600.3620/21.I103), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: measuring 42.5 mm in diameter, 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 60000 meters. At a glance, the dial balances texture and clarity: a black tone with matte finish, framed by stick / dot hour markers, and stick hands. At its heart beats a proven engine: the El Primero 3620 SC caliber. First released in 2025. 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.
