Titanium is one of the materials IWC first introduced to the watch industry back in the early 1980s and has several outstanding properties: only half the weight of stainless steel, it is corrosion-resistant, anti magnetic and particularly skin-friendly.
Among the new Ingenieur models presented by IWC at SIHH 2013, there are two titanium sport watches: the Ingenieur Dual Time and the Ingenieur Double Chronograph.
Both watches have a diameter of 45mm. Their design is characterised by the five screws that secure the bezel firmly to the case and by the crown, the crown protection and the push-buttons in titanium coated with rubber.
The new Ingenieur Dual Time Titanium (Ref. IW326403) shows the current local time on the dial. the white triangle in the outer 24-hour ring shows a second time and ensures that the wearer’s home time is always visible. To make it easier to differentiate between day and night, the upper half, from 6 p.m. to 6 a.m., is darker than the lower half. The Ingenieur Dual Time Titanium retails with a black rubber strap.
Unlike a standard chronograph, the split-seconds chronograph has two hands that start simultaneously. The rattrapante 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 synchronised with the other hand.
The sub dial at 12 o’clock” displays the chronographic minutes while the sub dial at 6 o'clock marks off stop times in half-hour segments. These recessed totalizers, resembling tachometers, give the watch an instrument-inspired look.
