it is being used to drive a micro bubble led display, the device is a very discreet timer of some sort. (says "single event")
no resistors, no caps, only a crystal, trim cap and a few buttons and switches..
made by Cronus

i did find this.. but no data on the IC itself.. http://electronicsusa.com/vintagestopwatches.html
yard sale for a dollar..
but the battery cover was missing and battery contacts corroded to death, i only bought it because it had one of them rare bubble led displays.
the guy wanted 3.00 for it, but i told him i'd give a dollar,, he went to 2 dollars. i said oki,, laid it down and walked off..a second later he said ok ok 1.00...lol
I've only seen those old style Bubble LED's on the old TI Calculators.
Well, have you tried subbing in 4.5Vdc to see if it still works?
From the link you provided.
It shows good working digital stop watches going for about $50 used.
So, if the battery contacts are the only thing wrong with it.
It might be worth cleaning it up, and replacing the battery contacts.
Find someone with a 3D Plastic Printer, and have them make a replacement battery cover.
it works, but the metal disk buttons are very worn out, barely working.. not worth saving...
even if it was working good, it'll most likely cost more to have a cover made then it's worth..
either that or EBAY
