spray drop of oil (WD40 etc), , probably dirt inside
I second this initial step as well.
Just in case you haven't done something like that on something so small, I recommend to spray the WD40 (or any penetrant equivalent) into a small cup/ramekin and then use a toothpick or small Q-tip to transfer the fluid to the spring bar. Makes it much easier than trying to manipulate the aerosol tip for pressure so to not make a mess of things in such a small area. Also makes less of a mess.
What type of spring bar tool are you using @jpeezy14?
Just as an aside, once you get them out, I believe the correct part # for bracelet spring bars is 068ST2207. If you have an OB near you, I'm sure they'll replace them for you no charge.
