With your seemingly growing watch collection, it might be a good idea to order some case tools and batteries. I stopped taking my watches to a jeweler about ten years ago, because the jeweler put a battery in my first Accutron the wrong way and said the watch didn't work. He obviously saw the Accutron battery is naturally upside down when he removed the dead battery. Now, instead of wondering if the jeweler damaged the case-seal (thin o-ring) or installed the wrong battery, I take my sweet time cleaning the seal cavity, back, and seal before installing the new battery. A jeweler's time is money, so they don't always do a very thorough job. The tools are fairly cheap and once you do a few battery changes, you'll have paid for the tools. Just a thought.
All you need is:
Case back blade(for pop off cases) - I use a strong pocket knife blade that isn't sharp.
Case back press (comes with a dozen nylon discs to accommodate any press fit case backs).
Case back wrench (go for the three side version, as the small two-pin versions like to slip out of the case back notches).
A set of super fine watch drivers(in case you need to remove a screw to get to a battery).
And an assortment of watch case seals (thin o-rings in various sizes/thicknesses).
