Introducing Zenith Defy Extreme (ref. 97.9600.3620/21.I300), a distinctive model that balances proportion, precision, and presence. On the wrist, the case feels purposeful: 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. Visually, the face is where character emerges: a black tone with matte finish, framed by stick / dot hour markers, and stick hands. Mechanically, the watch prioritizes accuracy: the El Primero 3620 SC caliber. Introduced in 2025. The silhouette offers presence without excess, lending confidence in a range of situations. Finishing showcases disciplined attention to detail across facets, edges, and surfaces. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
