Hello all,
I recently purchased a dead Sunwatch to see if I can get it working again and tonight I managed to open the case without too much damage. Problem is the all internals were pretty much turned to mush.
Luckily, the watch came with a bunch of parts and a brand new solar cell. I found a module/PCB that had a working display, IC and reed switches, but no solar cell. I've found some great info in the reference section here:

But I have a couple of questions:
How many wires are supposed to be connected to the solar cell? The one I have only has one wire.
If the one wire is correct, does this get soldered to the +ve location as indicated in the second link? I'm not sure if that circuit board is the same as the one I have.
If 2 wires are required, where can I solder the second one to on the cell, and where would it go to on the circuit board?
I've got a set of Varta V80 batteries coming from Mouser. Hopefully with the help of the forum I can get this watch up and running again.
TIA,
Mike
