The Ingenieur IW3808-BG (aka: IW3808BG), seen from the bench
The IWC Ingenieur IW3808-BG, born from Gérald Genta's 1976 vision, combines Swiss technical precision with functional design. The 42.30mm stainless steel case features an integrated five-screw bezel and magnetic protection up to 80,000 A/m. It houses the manual-wind caliber 69375 with column-wheel chronograph, date function, and small seconds. The 18mm lug width is sized to match the case proportions, requiring precise measurement between spring bar attachment points to ensure structural integrity and visual balance.
