A DOUBLE CHAMPION IN TITANIUM

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.

Rattrapante

The word “rattrapante” describes the split-seconds mechanism on a chronograph, which catches up with the primary chronograph hand. Unlike a standard chronograph, the split-seconds chronograph has two hands that start simultaneously. The rattrappante or split-seconds hand, which is superimposed on the stopwatch hand, can be stopped independently using a third button at “10 o’clock”, while the stopwatch hand continues to run. This permits the user to record two separate times, exact to the second, within any given minute. If the third button is pushed again, the split-seconds hand instantaneously catches up and is synchronized with the other hand. The process can be repeated as often as desired.
