Description

IWC’s designers took their inspiration for the Ingenieur Double Chronograph Titanium from materials typically used in Formula 1: titanium, ceramic and rubber. The split-seconds hand can be stopped to record intermediate times while the stopwatch hand continues to run, allowing users to record as many pit stops and lap times as they choose. Ref. IW3865-03 has a titanium case, black dial and rubber strap. It succeeded the IW3765-01 around 2013, with the biggest difference being the movement reference (79420 vs 79230) and the colors of the day & date discs.
