Sorry if im a bit ignorant of some blaringly obvious fact, i'm not too good at the old physics So its really just one big battery? and the water is the conductor?

It's powered in the same way that old potato battery science project that you had as a kid is. You have an anode and a cathode and they use the water as the medium for electron transfer between them. What really is going on is that you have a hunk of zinc touching one side of the water, and a hunk of carbon or copper or something else on the other side. The electrons are leeched from the zinc, through the water, to the other connection, and there's your current flow. It's not really powered by water, it's powered by a dissolving hunk of zinc. The water lasts so long because it's just evaporating slowly, as would any other container of water you could put in a room. When the zinc runs out, so does your clock.
