Introducing IWC Big Pilot (ref. IW3577-01), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in ceratanium and measuring 44 mm in diameter, with a thickness of 31 mm, defined by a round silhouette. The caseback is closed, and the crystal is sapphire, delivering water resistance to 10000 meters. At a glance, the dial balances texture and clarity: a skeleton tone, framed by stick / dot hour markers, and alpha hands. At its heart beats a proven engine: the 82915 caliber. Introduced in 2025. 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.
