Being a seasoned OzBargainer, and thanks to @WatchNerd, I now own quite a few watches. Most of them are high yield investments such as the Casio AE1200WH-1A.
However, it's becoming a chore to have to pay for their batteries to be replaced, so I'd like to know if anyone on here replaces their own batteries and, if so, how that works out.
