Did the old battery leak and damaged the circuit board?

Can you post some photos of where the buttons make contact on the circuit board. 

Try cleaning the gold fingers on the board with alcohol and also the conductive rubber strips behind the LCD display panel.

A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

Try putting everything back together and closing the back cover.

I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.

I think you are right wish one of the two spring should make contact do you know what one?

Usually the coiled spring contacts the piezo sounder and the finger spring is the ground.
