SOURCE: How do I change the battery of a Jules Jurgensen pocket watch.

First you have to get an eyeglass and examine watch caseback. Can you see the joint or is it monoblock? If there is joint, get strong knife and press into it. Some of watch casebacks are very tight, so, apply great pressure but do not let the blade slip or you will damage the movement.
If the case is monoblock, then you have to open it from dial side.
Be very carefull when doing it as any slip of the blade will damage your watch.

Good luck.
