the watches are very nice, although i wouldnt personally buy one.
One thing that I think could be improved are the sports watches. the movement could have been 1000 times nicer. if i were designing it id replace that ugly oscillating weight with an AP royal oak style one, maybe with some horses with polo players engraved on it.
I agree that maybe in a few years every one will be wearing one like the numbered polo shirts 
Fashion watches are very popular in my country (the UAE), the Chanel watches were sold very well a few years back when they were popular. Gucci watches continues to be a best seller amongst the younger generation, so I wouldnt be surprised for the Ralph Lauren watches to be sold out there, although the high price of the stirup model would be a problem if RL was looking for very high sales...
Thanks for writing this review, it was very enjoyable to read and had very good insight into a possible future for RL watches.
