I thought since I was going to open mine up and a few people have made comments, I would use this as my first opportunity to give back to JF.
Here is my stock clock, next to a 9V for size.
To access the clock, you need to slowly open up the pop metal ring. start by slowly working around just moving the edge a little, then start slowly prying it up. I went around the clock 5-6 times before I got it completely opened.
Once the edge it pulled up, slowly start working the screwdriver between the chrome ring and the clock base.
Once this is done you can pull the chrome ring off, and this is what it looks like laid out:
you have the knob to adjust the timing (just pull that straight off), then the lens sits in the chrome ring with a thin gasket, then a metal detail/spacer ring (has the white stripes on it) then the actual clock unit.
Now you can pull the second hand off. Then slip the minute and hour hand off. Be gentle as it doesnt take much to break them!
You can now pull the face off by bending the 3 tabs on the face that link to the clock unit. I just put my needle nose against the tab and bent it.

Now you should be able to work on the clock. I hope the writup works for some people. If I can educate some then im on the right track!
