Replacing a Tissot Generosi-T Watch Battery(Size = 377 or IEC SR66) T007.309

In this quick video, I show how you use a knife, press it directly into the interface between the back plate and the case, remove the plate, and replace the 377 metal oxide battery. The battery actually can come loose easily, and they should have added a piece of foam on the back plate, one can do this easily if you've had problems with the battery coming loose and the watch stops working.
