content: Sigma watch has a very poor quality. I bought I PC7 one year ago and the first time I put it under the shower it stops working (it was supposed to be 3m water resistance). I sent to sigma and I have to pay for all transport expenses from (From China to Brazil).After 1 year the battery is down and the back is rusty (I have a 10 year old Casio watch that is used in swimming in pool and seawater and does not have any rusty).Don't recommend Sigma watches.
