Update: Thanks to Your Help, I Was Able to Fix My Clock!!!
I am thrilled to share that thanks to this helpful, resourceful community I was able to save my clock! (my question: http://www.hometalk.com/26826748/q-help-i-love-this-clock-but-the-battery-won-t-stay-in-place)
I tried a compilation of you suggestions and I think it was all important for the end result.
As a I examined the battery pack part of the clock, I noticed that the seconds' hand was getting caught in between the glass and and the minutes' hand.
So...I removed the glass. I unscrewed the clock frame, took out the glass, and returned the frame.
And now it works and still looks great. Thank you all very much!!!
I removed the glass
Its returned to its former glory!! Thank you for your help!!
