How do I open the case of a 1968 automatic, ambassador Bulova watch? It appears that there is no way to open the back.

Question edited for clarity, spelling of Bulova.

It is a quality watch. Contact Bulova direct, and get it serviced as well, replace gaskets etc.

Most of the time you can find the serial and or model number on the first link that is attached to the case of the watch on the back. Often there is a serial number on the back of the case itself. If not in any of these locations you may have to open the case and look on the inside of the case. Be careful with opening case, if you're not comfortable opening the case yourself take it to a reputable jeweler.
If there are no serials on the watch it is probably a knockoff or replica.

Hope this helps.

You need a special tool called a case opener, if you flip the watch over you should see 6 square slots on the outer rim, this means that the back case is screwed on and probably has a water proof seal, keep in mind there are different sizes. I suggest you check ebay for watch tools, you might find what you are looking for.

Hi. If you take a tiny screwdriver (one that you might use to screw a screw into an eyeglass and run it gently around the back you will feel an indentation where you can insert the tip and pop open the back. The battery is easy to access but trying to get the back back on is the problem! Good Luck.
