At first that was a small let-down, as the previous Iwc Ingenieur Uhrwerk Replica Ingenieur mention 3227-01 was in precisely the exact same ball park but with an in-house motion. However, when I gave it some thought, I realized that this was almost 10 years earlier and prices did increase a bit over the years (as we all know). If IWC would have put their in-house fabricated movement within this fresh IWC Ingenieur reference 3239 the price would have been closer to $10.000 Euro likely, like we’ve seen on a few of their other collections and models.The IWC Ingenieur isn’t also really concerning the motion — as long as it is mechanical — however about its own aesthetics and performance. The watch was developed to be able to play in an environment surrounded by magnetic fields (up to defy 40.000 A/m which equals 500 gauss) because of the use of a soft iron interior case.That is afar from your Rolex Milgauss and even much further from Omega’s caliber 8500 family of movements that are able to withstand 15,000 gauss (~ 1,200,000 A/m). Although I am convinced that magnetism is going to play a larger role later on, since we all use tablets, smartphones, laptops and so on, I need to say that I have worked in an IT environment for a couple of years and never experienced any issues using magnetism.Anyway, the motion that IWC sourced is the aforementioned Sellita SW200 and is based on ETA’s 2824-2. A solid movement that performs just like a diesel. No transparent caseback needed in my opinion, but that would not match this type of watch in any case due to its ‘instrument’ purpose.

The Ingenieur Perpetual Calendar Digital Date-Month is the flagship of the Ingenieur family. The design is inspired by the very first Ingenieur models and features a simple round case and polished bezel. The perpetual calendar with large digital date and month displays, which can be easily set using the crown, recognizes the different lengths of the months and takes into account the leap day every 4 years. The IWC-manufactured 89801-calibre movement also features a chronograph function. This timepiece has a 45-millimetre case made from 18-carat red gold, a silver-plated dial, black hands and a black alligator leather strap, and is limited to 100 watches.
