Brought a IWC watch during my last Dec 2012 trip to Europe... The sales told me the watch is a IWC376421, even the warranty card is written IW376421... Recently, read more on the 3764 series and discover that I was given the IW376403... Understand that 376403 is already obselete long time ago, how come the IWC boutique still carries the obselete model? I didn't buy from parallel importer but from the IWC boutique(price paid was for the 376421) and this can happen!! :-(
