The last time I went to my AD for a battery change for my Tag Aquaracer, I was charged $20. So, I decided to do it myself. It's not complicated as long as you have the proper tools.
I purchased a variety of sturdy instruments that will pay for themselves as soon as I do all my quartz timepieces.
I first started on my cheapies for practice and will move on the more expensive ones. No more trips to the AD. No more waiting and saving money in the process.
