Hello there. My wife has an old Citizen 6031 watch which probably hasn't been used for at least 10 years (was belong to her late father) and after changing battery and not getting any reaction I've taken it to a repair and the gentleman basically put a drop of some liquid on it which made it works for about 5 minutes and then stopped working again. My question is could it be that the oil dried after many years of not working or how to go about trying fixing it? I have ordered a new equivalent movement which I am waiting for, but for my practice I just wanted to try to fix it even though it doesn't pay. Thank you for your assistance.
