I have just a new battery installed in a ladies C & V radio controlled watch. I have followed to the letter the instructions, 5 times in all. I have pressed the right buttons, left it on the window ledge away from TV, Radio, Computers etc. When I go back to it in the morning some 12 hours later the watch is ticking merrily away and keeping perfect time but it has not calibrated to the right time.
