I have noticed that too. I think it might have to do with the fact that IWC no longer offers any other language than English on their own day wheels (they do have their own with a slight difference from the standard ETA). If I remember correctly this stopped right before the release of the 3717.
Update: Been using the jacket for about a month now in windy minus degrees (celsius) with snow and I must say I'm very impressed with it in terms of keeping me warm. Of course I wouldn't use it while being on a Antarctic expedition since my life would depend on it - but as a fashion garment in the city during winter I can highly recommend it!
