Most pocket watches open in the back. Usually you have to have a very thin bladed instrument to pop off the back of the case. Since this is a gold watch I would take it to a jeweler to look at it since it is very easy to scratch up the case if you aren't careful.

Possibly the mainspring has been broken. I am guessing that you cannot see what has come loose. The only way is to open the case back and see. If that is what has happened then it can be replaced.

The best thing to do for instructions for a Jules Jurgenssen is to contact them. You may also try retailers who carry their product.

First -let's check out what type of watch you have. If you push the crown in and it turns freely back and forth with no resistance at all - this is battery driven watch.
If you do the same and feel and hear some clicking and resistance- this is mechanical (spring driven) watch.
Next - the case: Usually all pocket watches have snap-on casebacks. Take an eyeglass and examine the case. Even if you think there is no any grooves or gaps- try to pry it using watchmakers caseback opener (about $5 on ebay).
In case if there are no chance to open caseback - that means you have one of the cases assemblad watch glass fitted last and that means you have to take glass out first and then only to get to the movement.
As you will not be able to get the glass out without braking it, the only solution will be to visit your nearest watchmakers shop and ask for help.

Rate, please.

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.
