It's just terrible. It took more than two months to repair the watch, and they tried to pick it up three times, but had to return it because it was out of order. As a result, I took it away, but after a couple of days the clock started to stop, I'll have to look for another workshop. My advice is to pass by. The clock is self-guided.
The result of replacing the O-ring in the watch by the master of the center, 2 minutes in the pool and such a result. They returned the money for the work, said that it was not their fault and the water got through the button, which is recessed, although it is always recessed, such a design. At the Casio service center, I was told that this was due to incorrect selection of the O-ring and repair only by replacing the entire mechanism.
