The Ingenieur IW3808-BM (aka: IW3808BM), seen from the bench
The IWC Ingenieur IW3808-BM is a stainless steel chronograph from the 2000s, evolving the 1955 collection designed for engineers requiring antimagnetic protection up to 80,000 A/m. It features a 42.30 mm diameter case with the characteristic porthole, a Swiss functionalist design by Gérald Genta, and the IWC 69375 automatic column-wheel chronograph movement. The 20 mm lug width accommodates versatile strap compatibility while maintaining proportional balance without excess.
