IWC Watchmakers service Gérald Genta’s Ingenieur SL “Jumbo” (Ref. IW1832)

This Ingenieur SL “Jumbo” Ref. 1832 dates to about 1976, making it nearly 50 years old. Last serviced eight years ago, it arrived with pronounced scratches and deep dents – particularly on the case – requiring extensive restoration to return it to its original geometry. The Ingenieur began in the 1950s as IWC’s first antimagnetic watch for civilian use, but it was the 1832 that transformed the model. Designed by Gérald Genta – widely regarded as the most influential watch design of all time – the “Jumbo” introduced a striking visual identity with its screw-on round bezel with five recesses, patterned dial, and integrated H-link bracelet.
