I bought this watch and it was returned because the watch was not in its box but delivered in a plastic bag, the bracelet was not mounted and I was unable to do it, there was no certificate certifying that it was authentic or even international warranty. I bought this watch but still more expensive in another shop with all certificates. Nice watch, accurate and above all it imposes, it is very thick. Storing the instructions to use the calculation rule. I noticed the watch by it but not the same care provider related to this purchase was thanked.
