If you plan on doing it multiple times and want a quality tool you should look into the Burgeon Spring Bar Tool. It’s expensive but I’ve found that it’s better to buy a quality tool to work on your hobbies with rather than a cheaper option that may break or damage what you’re working on.
If that’s too expensive, this one is made by the same company and is almost 10x cheaper. It just does one side at a time instead of both
Oh ok, that's cool. In that case it's basically how much money are you willing to invest in it. Unfortunately there are not really any "medium" quality tools out there. At least not that I've found anyway. That being said, these relatively cheap tools have served me pretty well.
shitty watch press This thing is actually pretty great for everything except trying to put a crystal back in evenly. Might take a few very gentle attempts. But bezels, no problem. Crystal removal, no problem.
screw off case back opener Can't beat the simplicity. No ridiculous sliding nut and bolt mechanisms. Just a simple spinny wheel.
hand press Gets the job done. Comes with a set of hand pullers which I never use.
spring bar tool Worth its weight in gold. This is actually a great piece of equipment. Heads are replaceable.
movement holder Pretty much a necessity.
shitty kit This has a lot of crap but for the 3 or 4 things you'll get in here which are not too bad I guess it's worth the money.
If you want more serious tools (maybe you're a baller idk) there's http://www.ofrei.com/ and http://www.esslinger.com/ where you can find most of this stuff. But you can also spend several hundred dollars on a single tool on these sites.
