Thanks to all responders. I also have both automatic & quartz watches. It seems as tho every time I decide to wear a quartz watch, it's needing a battery soon after, if not immediately. I have taken to popping the stem out, stopping the movement which I think then makes the battery life close to shelf life. My problem is I have a number of different watches, some cheap, some not so cheap and I have no idea what battery Is needed in each case.
So, I guess it's a two step process. I will carry on, thanks again to all.

BTW, I do have the tools.
