Recently, IWC has been improving the Ingenieur collection in a variety of ways. The IWC Ingenieur Perpetual Calendar Digital Date-Month is a brand new addition to this collection, and is noted for the complications incorporated in to it. IWC launched this model at the SIHH in January 2013. It does have elements of tradition incorporated in to it in a modern way.

This new model from the watchmaker does have a lot of similarities with one of their other models, the IWC Spitfire Perpetual Calendar Digital Date-Month. In fact, the new model is based on this existing complication. But, they revamped it to provide it with a modern air as well as aesthetics. So, you can call it an Ingenieur buddy of the Spitfire. Those of you who are familiar with the Spitfire must be familiar with its relation to the Pilot collection. In a similar manner, this new watch has its Ingenieur attributes associated with it.

On close inspection, you may find some resemblance to the rotor of the watch with that of Hublot F1. Of course, the IWC rotor has the look and feel of a wheel rim than the Hublot F1.

The watch has a lot of elements incorporated in to its dial to make it in to one of the busiest watches ever seen. Still, its resemblance to an aircraft and the perfection of the design adds to its appeal.

If you have been following IWC for many years, you would certainly find some significant changes from its original aesthetics. Now, the watchmaker is following its design aesthetics a bit on the lines of Hublot and Breitling.

The watch has a 45 mm size case made of the alloy titanium aluminide which is typically seen in automobile turbines as well as aircrafts. Why are they using this alloy in place of titanium? Titanium aluminide is a lot lighter than titanium and is also much stronger. Thus the watch benefits from both these aspects. Another interesting material used for the creation of the watch is zirconium dioxide that is used for all the black colored parts. This material is commonly used in Formula 1 car racing for its positive aspects.

The semi-transparent sub dials made of sapphire sitting over the digital display discs allow you to view the watch movement in action. The power saving aspect of the watch comes in to effect at midnight. At this time, the discs do switch over and saves a portion of the energy needed for the end of month to move the month disc. In a similar manner, stored energy adds up for the end of the year activity that needs a lot more energy to move all the displays at the same time. Of course, it would be a visual treat to see it all moving at one time!

The strap is made with rubber as well as clothing elements incorporated in to it.

The perpetual calendar of the watch does have its unique features like digital date and month displays. It has the ability to show leap year accurately until the year 2100.
