Discover IWC's precision with the GST Aquatimer (ref. IW3580-02), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in titanium and measuring 45 mm in diameter, with a thickness of 20.5 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel. The caseback is closed, and the crystal is sapphire, delivering water resistance to 20000 meters. At a glance, the dial balances texture and clarity: a black tone, framed by stick / dot hour markers, and stick hands. At its heart beats a proven engine: the 80110 caliber. Introduced in 2014. 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.
