The standard 3714 (or whichever model is the standard Portuguese Chrono) has actually been very popular for 20 years or so. It is just old. It is the IWC watch of choice as I have noticed in the EU over a number of years. More Chairman and CEO's seem to wear that than anything else from IWC. Frankly, it seems to be more popular than the Pilot series over there. At this point the issue is how many additional sales can be made after 100 different editions. The 7 day Portuguese was invented to charge more and sell more.
