The Ingenieur IW3807-01 (aka: IW380701), seen from the bench
The IWC Ingenieur IW3807-01 chronograph features a 42mm grade 5 titanium case with antimagnectic protection up to 80,000 A/m, paired with a 20mm lug width. It houses the IWC 69370 calibre, an automatic column-wheel chronograph movement with date indication and small seconds. The 42mm case and 20mm strap measurement reflect ergonomic design principles developed since 1955 at Schaffhausen, combining technical function with rational aesthetics.
