In FORMULA ONE, lap times provide important information about various technical parameters and the progress of a race. During qualifying, the driver with the fastest lap time is awarded pole position. So it was clear that the Ingenieur collection, which is deeply influenced by the cooperation between IWC and the MERCEDES AMG PETRONAS Formula One™ Team, should feature a double chronograph. The split-seconds hand can be stopped to record intermediate times while the stopwatch hand continues to run. If the push-button at “10 o’clock” is pressed a second time, the split-seconds and stopwatch hands are resynchronized. This allows the user to record as many lap times as he chooses. For the Ingenieur Double Chronograph Titanium with the 79420 calibre, IWC’s designers took their inspiration from materials typically used in Formula One: the casing ring is made of titanium and the striking screw heads in the bezel are made of ceramic. The crown, the crown protection and the push-buttons are lavishly coated with black rubber. The totalizers, which closely resemble tachometers, give the watch a consistent, instrument-inspired look. The watch is available with a silver-plated or black dial and normally worn with a black rubber strap.
