The IWC Ingenieur Automatic 40 ref. IW328903 is a 40 mm stainless-steel sports watch that reinterprets the distinctive design language of Gérald Genta’s Ingenieur SL from the 1970s. Its aqua-coloured dial features IWC’s structured “Grid” pattern, while five functional bezel screws, an integrated H-link steel bracelet and a combination of polished and satin-finished surfaces give the watch a strongly architectural character. The case measures 10.7 mm thick and offers 10 bar of water resistance.
Inside is the IWC-manufactured calibre 32111, an automatic movement operating at 4 Hz and providing an extended 120-hour power reserve. A soft-iron inner case protects the movement from the effects of magnetic fields, preserving an important technical element of the Ingenieur identity alongside modern movement construction and everyday usability.
Reference IW328903 is particularly distinctive within the Ingenieur Automatic 40 family because its aqua dial adds a more expressive visual character to the otherwise technical steel design. The integrated bracelet, compact proportions and historical connection to Gérald Genta’s Ingenieur SL make it especially relevant for buyers considering contemporary integrated-bracelet sports watches with a strong design lineage and a practical five-day power reserve.
