My Tissot watch was out of battery and i happened to be there shopping with my wife thinking they carry Tissots so decided to have battery changed there. He said titanium watch cost 20 dollars and took 15 minutes. I thought it was a little expensive but since I was there so I went ahead and had it changed.
Later, i went to pick up my watch and turned it over, the back case was not closed all the way which was not a big deal, but there was a dent on the edge where he used the tool to open the back case. i asked my watch collector friend and he said he might used the wrong tool or very careless and inexperience. After all, the watch cost about $450.
