The Ingenieur IW3808-BU (aka: IW3808BU), seen from the bench
The IWC Ingenieur IW3808-BU is the contemporary evolution of an icon born in 1955 as an antimagnetic instrument for engineers and scientists. The 42.30mm stainless steel case and integrated bracelet create a compact visual architecture. The IW3808-BU houses the IWC 69375 calibre, a column wheel chronograph movement ensuring precise regulation and smooth function transitions. The 20mm lug width is historically characteristic of this model and defines compatible strap offerings.
