An easy watch for IWC lovers to enjoy is this new model in the Ingenieur collection that incorporates a lot of what we enjoy about the brand. This may be the first time, or among the few times that IWC has used its rattrapante movement in an Ingenieur piece. Rattrapante is a fancy name for a split second chronograph, or as IWC refers to it in this watch, a “Double Chronograph.”

Double chronographs are an interesting complication that are mechanically very cool, but probably not something most people are going to use very often. They offer a second chronograph that measures up to 60 seconds outside of the timing of the main chronograph. When not being used, this second chronograph hand usually “hides” under the main chronograph seconds hand, until you want to use it to time something else. Watch nerds can go ga-ga over these, and they actually aren’t that common, though you’ll find a good variety of them in various IWC watches. Now it has come to this collection with the IWC Ingenieur Double Chronograph Titanium.

IWC is well known for its insatiable appetite for engineering excellence. Therefore, it was inevitable that with its masculine persona and expertise, use of cutting-edge materials, such as ceramics and carbon-fibre, IWC would eventually enter the octane fueled world of Formula One. The Ingenieur is this year’s motorsport inspired collection from Schaffhausen. It takes inspiration from the historic model of the 1950s, but embraces the modernity exampled along the pit lane. If ever there was a watch that was the perfect metaphor for competitive wheel to wheel action, then it has to be the Ingenieur Double Chronograph Titanium. Formed of titanium and designed for measuring crucial lap times, the watch is perfectly at ease with the intended symbolism.

The silver tincture matches the gleaming bodywork of the cars driven by Hamilton and Rosberg on race weekend. It proffers a cool canvas to display time, providing welcome respite from the rising cockpit temperatures. The hour and minute hands are partially open-worked, with apertures adjacent their fulcrum. The tips are solid and lined with luminous material.

Hours are marked with black batons with luminous centres. They confer information with brevity and clarity facilitating user-friendly, expedient read-off. At 3 o’clock, the day and date are presented in two adjacent apertures.

A 12-hour chrono counter is located at 6 o’clock. At the centre of the subdial, text confers the water resistance of the timepiece, 12 bar (120 metres). The hand on the chrono- counter is black and tipped with a luminous equilateral triangle. A similar 30-minute chrono counter resides opposite, below noon. It shares the design language of the 12-hour chrono counter but features a hand which jumps in discrete one- minute stages.

Subsidiary seconds are located at 9 o’clock. The seconds hand includes a hacking seconds facility, a feature found on many of the historical IWC timepieces which punctuate its history including the iconic pilot’s watches of the 1930s and 40s.

This timepiece is a split seconds chronograph, sometimes referred to as a rattrapante or doppelchrono. Unlike a standard chronograph, the split seconds chronograph has two hands that start simultaneously. The split seconds hand, which is superimposed on the stopwatch hand, can be stopped independently by pressing a third push button at 10 o’clock, meanwhile the stop watch hand continues to run.

This complication allows the wearer to time two separate events precisely. If the third push button is pressed again, the split seconds hand immediately catches up with the stop watch hand and continues to run in tandem.

Titanium is one of the materials that IWC have embraced with the Ingenieur collection. It is a material which is strong, yet light. These qualities have seen it used successfully in the aerospace and medical industry as well as Formula One. In the case of watch manufacturing, other qualities make it highly desirable. It is corrosion resistant, anti-magnetic and skin friendly.
