Zenith led & analog so nice and yet so dead!

Gentlemen :
I need some help now . I just got a nice zenith led & analog
like the one seen here on the right :( not the square one ,futura)
http://www.ebay.com/itm/1971-Zenith-LED ... 4842a191e0

I opened and i discovered that the batteries had leaked . And the metal contacts were disolved by the battery acid .So now they are gone ,the rivets are still there !
How would you tackle the restoring on that watch ?.It seems very complex to disassemble.

Four screws around the edge of the module are holding down some clips that swing into a groove - pull the screws, lift the clips out of the way. THe movement is a tight fit into the case. Bad news is the motor of the analog portion - largely unsealed, relatively crude construction (IMO). Yeah, some guy sent me a dozen of those that were NOS but had batteries in for all the years. Only 2 survivors, and even those were dodgy. Wishing you better success on yours.

Thanks Ed
I had done that already . I discovered that the contacts are (rivets included
) are not heavy gold ,but just covered with layer of gold .As a result the substrate ( maybe copper or brass ) rusts completly away leaving some trace of contact with gold on top.But is not making good contact .So all has to go .How to make a new contact with rivet is the next step
