Meet Fortis Cosmonaut (ref. 638.28.13), 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 15.5 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel, protected by pvd coating. 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 arabic numerals hour markers, and stick hands. At its heart beats a proven engine: the 7750 caliber. 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.
