Experience the craft of Zenith in the Revival (ref. 03.A3648.670/21.M3648), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 37 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 Elite 670 caliber. Initial production year: 2024. 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.
