Experience the craft of IWC in the GST Aquatimer (ref. IW3538-04), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in titanium and measuring 42 mm in diameter, with a thickness of 14.8 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel, delivering water resistance to 200000 meters. At a glance, the dial balances texture and clarity: a black tone, framed by stick / dot hour markers. At its heart beats a proven engine: the 30110 caliber. Introduced in 20042009. 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.
