Salemyang,
Thank you for sharing your observations!
Your findings fascinate me because they are exactly opposite to my observations. However, I might not the in the best position to say so, because I am not a industry specialist. It is just something that struck me at SIHH and forums.
IWC has always had (relative to the market) some big watches in the collection, The Portugieser has always been a large watch. Even the Ingenieur of the 1960s was relatively large with its 36mm. When fashion started to meet "simplicity and functionality" watches became bigger and bigger.
Not too long ago IWC seemed to deviate from its "simplicity-functionality" roots by producing bulkier, modern, fancy looking watches. Some believe that had to do with the booming Eastern European market and the needs of the customers. There are not a lot of watch companies who did not jump on the same bandwagon. And frankly, one may like it or not, but that is what keeps businesses profitable.
More recently IWC seems to go back to its roots again with simpler, cleaner looking watches. The Portofino line and the new Ingenieur line are examples. Again, some believe that may have to do with the needs of Asian customers. I do not know if that is true but other vendors do the same thing.
So basically, I observe a different trend in IWC's and other vendor's collections. And I can't blame IWC for monitoring customer needs closely. In fact, it's a smart thing to do. We also can't blame IWC for riding the Limited-Special-OneTimeOnly-Edition wave because that is what we, customers, apparently ask for!
Just my two cents.
Peter
