So I have a ~9 year old Citizen watch that is branded OP (Olym Pianus) that my grandma bought for me in Taiwan when I was visiting.
The battery has been dead for a while because I don't want to have a 3rd party replace the battery and put ANOTHER fat scratch on the back.
My tools are coming sometime next week. I'm wondering if there is a certain type or brand of battery that is best to get? Or a good online seller from amazon or ebay? Thanks!
