I buy many watches from amazon, directly from them or supplied through them. I choose watches, then 70% off. I have never had an issue with the purchase experience, but I have never owned a Raymond Weil.
Be careful if you do the percentage off search. There are a lot of junk watches that were marked up so high, that after the big discount it still doesn't represent a good value.
This might be my next one.
