That doesn't surprise me. Back in the dim and distant past, I worked in a store where one of my jobs was changing watch batteries. I was given a Watch Back Remover tool and shown once how to use it: that was the full extent of my "training". So, if we got a watch that didn't have a standard back, we just wouldn't bother with it. However, for the G-Shock, it looks like it's a really straightforward job that should take you 5 mins to do yourself. Looks a lot easier than any laptop repair/replacement job for example: https://www.youtube.com/watch?v=hGkFYVpDv-k https://www.youtube.com/watch?v=hGkFYVpDv-k
