IWC Schaffhausen – Ingenieur Double Chronograph Titanium (Ref. IW386501, IW386503) & Ingenieur Dual Time Titanium (Ref. IW326403)

Materials used in Formula One™ inspired the cases of the Ingenieur Double Chronograph Titanium and Ingenieur Dual Time Titanium. Technically speaking, too, the two timepieces are ideal for the motorsport’s premier discipline. While the Double Chronograph records lap times, the Dual Time helps to keep track of the time during the racing season despite constant time-zone changes.

The new design line in the Ingenieur watch family is easy to identify: instead of the characteristic bores, the bezels of these distinctive sports watches feature five screws. These secure the bezel firmly to the cases of the Ingenieur Double Chronograph (Ref. IW386501, IW386503) and the Ingenieur Dual Time (Ref. IW326403), which are made of titanium.

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, antimagnetic and particularly skin-friendly. In both watches, therefore, the crown, crown protection and push-buttons are made of titanium, which is painstakingly coated with rubber.

In Formula One™ racing, lap times provide information about technical parameters and the course of the race. During qualifying, the driver with the fastest lap time is awarded pole position, on the inside bend at the front of the grid. So it was clear that the new Ingenieur collection, which is dedicated to the partnership agreement between IWC Schaffhausen and the MERCEDES AMG PETRONAS Formula One™ Team, would have to feature a double chronograph.

The split-seconds hand can be used to record two intermediate times within a given minute while the stopwatch hand with its blue or white tip continues to run. When the push-button at “10 o’clock” is pressed again, the split-seconds hand instantly catches up with the chronograph hand and runs synchronously with it once again. In this way, users can record as many lap times as they choose. The stopwatch display at “12 o’clock” is divided up into 30 minutes and contains a jumping minute counter. In the course of an hour, its triangular tip completes two revolutions.

The hour counter in the totalizer at “6 o’clock” marks off stop times in half-hour segments. The recessed totalizers, which closely resemble tachometers, give the watch its consistent, instrument- inspired look. With so many displays, it goes almost without saying that, apart from the date, there should also be one for the day of the week.

The Ingenieur Double Chronograph Titanium is water-resistant to 12 bar, available with either a silver-plated or black dial, and worn with a rubber strap.

The new Ingenieur Dual Time Titanium takes the hard work out of it by showing a second local time of the wearer’s choice. On the dial, we see the current local time. This can be advanced or moved back in one-hour steps, even beyond the International Date Line.

While the white- tipped seconds hand relentlessly circuits 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.
