IWC Ingenieur Dual Time


As an Official Engineering Partner of the MERCEDES AMG PETRONAS Formula One™ Team, the Swiss watch manufacturer has been inspired to create another piece of haut horlogerie, the IWC Ingenieur Dual Time.


The IWC Ingenieur Dual Time has a stainless-steel case with a diameter 43 millimetres. It seems rather understated when compared with the larger Ingenieur models. But the feature that puts the Ingenieur Dual Time at the front of the pack is its ability to display a second local time of the wearer’s choice. Current local time is shown by the hour and minute hands on a dial available either silver-plated or in black.

The time can be advanced or turned back in one-hour steps via the crown, even when crossing the International Date Line. While the seconds hand with its pointed red tip goes around, the second time – the time at home, for example – is indicated by another hand with an arrowhead tip on the outer 24-hour ring. To make it easier to differentiate between day and night, the top half of the ring, from 6 p.m. to 6 a.m., is darker than the lower half. The striking bores in the bezel were the brainchild of watch designer Gérald Genta. In the case of the legendary Ingenieur SL (Ref. 1832) from IWC Schaffhausen, unveiled in 1976, he placed the five functional holes directly on the rim itself, where they originally served to hold it firmly in position. These bores and the entire case architecture rapidly established themselves as the hallmark of the entire Ingenieur family.
