My Newish Hamilton Quartz Khaki Field recently developed a problem whereby when I got up in the morning the watch would be somewhere between 5 and 30 mins slow. The problem has now deteriorated insomuch as the watch now stops at about 18 mins before midnight (date change). The second hand goes forward by one second and then back one second, then forward one second, then back etc. and so it effectively has stopped.
When I reset the watch it works perfectly well until it approaches date change again.
Do I need to replace the movement? and if so would that definitely rectify the problem?
I would be hugely grateful for any advice.
