Introducing Zenith Defy Extreme (ref. 97.9600.3620/21.I001), a refined timepiece that blends thoughtful design with reliable performance. A study in proportion and durability: 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. The dial composition is deliberate and legible: a black tone with matte finish, framed by stick / dot hour markers, and stick hands. Beneath the caseback lies dependable performance: the El Primero 3620 SC caliber. First released in 2025. Comfort and balance define the wearing experience, making it an easy daily companion. Subtle transitions between textures elevate the overall impression. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
