A rare neo-vintage chronograph from IWC’s legendary Ingenieur line. Compact, rugged, and unmistakably designed with Gérald Genta’s industrial DNA, the Ref. 3805 embodies late-90s design at its finest.

This reference stands out as a high-end quartz chronograph — powered by the precise and reliable IWC Caliber 631 (based on ETA 251.262). It delivers battery-driven accuracy while retaining all the hallmarks of the Ingenieur family: tool-watch toughness, integrated bracelet design, and the signature five-screw bezel.

With its black tri-compax chronograph dial, luminous Arabic numerals, and bold red chronograph seconds hand, the 3805 balances professional utility with a sporty edge. Produced in limited numbers in the 1990s, it remains an underrated sleeper among IWC collectors — especially those who appreciate neo-vintage quartz in a luxury context.
