I purchased the watch, Cartier Men's W6920047 Ballon Bleu Steel and 18kt Gold Watch, on 4/11/2012. I wore it for two weeks, and it worked fine. I then put it back in the box until recently. I wore again on 10/3, and the watch was running slow. It slowed about 5 minutes after 2 hours. The watch is basically useless.
I called Amazon service department after 3 watch less weeks on an oversea trip, they told me I have to send the watch to KY at my own cost, and it will take 4-6 weeks to get it fixed.
I am very unhappy about the watch and the experience.
