IWC 1832 Ingenieur SL Jumbo SS Black Dial

Introduced in 1976, the IWC Ingenieur SL Reference 1832 is a Gerald Genta-designed masterpiece that redefined the luxury steel sports watch. Often nicknamed "Jumbo" for its bold 40 mm case, this model features a distinctive screwon round bezel with five functional recesses and an integrated Hlink bracelet that exemplify Genta's architectural vision. Powered by the automatic calibre 8541ES with Pellaton winding, stopseconds, and antimagnetic components, the movement is protected within a softiron inner case and cushioned by rubber buffers-an impressive technical feat for its era. With production limited to around 543 steel examples, the SL 1832 remains exceptionally rare and highly coveted among collectors. Its textured black "waffle" dial adds both depth and visual intrigue, while the robust yet elegant profile speaks to IWC's engineering prowess. As the flagship of the SL collection, this model embodies the convergence of avantgarde design and technical innovation, securing its status as a cult classic in the pantheon of vintage sports watches. Excellent condition with IWC service box and original IWC certificate dated 1979. Also comes with service papers dated 2017 and 2020.
