So I took my DW 8400 today for a battery change since it was getting a bit weak. After the fresh battery was installed the watch didn't want to work. I read the how to change a battery on a G-shock sticky and was wondering if it only needs a reset ( going back to the shop tomorrow and will have them do it just in case). I was under the impression though that by just changing the battery the watch should start up again or am I wrong? I hope my watch didn't get fried as I really like it and finances are a bit tight at the moment for a replacement.
