I have owned my Raymond Weil Two-Tone "Parsifal" watch for over 13yrs and I LIVE in it 24/7. I only remove it when showering. I have never had any issues except the changing of batteries. (which I believe has been a total of 3 times) The crystal (face) remains without any scratches. (again, I clean, cook, sleep and LIVE in my watch) My only regret is that I did not get the Diamond model above, as mine is the plain one. At the time....this Diamond one was selling (average) for around $1500 and the absolute best price I could have bought it for was $1350. So, now, years later....you can buy this great watch for even LESS! (go figure?) BTW: many of the competitor, expensive watches are only quality, gold-plated w/real diamonds, but this is actually 18K and a much better overall value! Compare with knowledge and you will be happy with your purchase!
