This tool worked perfectly!

I have watched some jewelry-store guys open my watches before to replace the batteries, watching usually from a distance, noticing all their magnifying lights and ultrasonic cleaners and really nice tools, how impressive they looked.  But with this little blue tool I opened 'er up, then out with the old and in with the new.

I know I am cutting into some jewelry guy's livelihood by doing it myself but, sorry, it was fun.  Saved a few bucks too.  Probably many bucks by not letting wife near a jewelry store unnecessarily.
