While most non-solar g-shock's take the CR2016 battery, some are quite odd in the batteries they take. Sure you can open up the back take out the old one(s), seal it up, order and repeat, but I'd rather do all that once!
So, I'll start it out with a model or two that don't take the CR2016. Feel free to post the CR2016's too, for completeness.
DW-9100 Riseman: CR2016 (I thought there would be more than one battery, but not so)
MR-G 130T: SR920SW and SR621W or SR621SW
I'll add more but maybe we can make this a Sticky (the old sticky has a link that doesn't work).
