Hello guys, after a few weeks of reading and learning tons from this wonderful forum, i got myself a rep, its a beautiful watch and made really well but, i am having some problem with the movement, i tried to look for same problem from others but cant really find something related to my problem, the movement is working pretty good through out the day, keeping good time, however the problem starts late at night where the hour and minute hands will stuck around 10.50+PM, after adjusting the hands forward about 11.20PM its works fine once again, also the small seconds seems to work without any problem..its weird that it have no problem at all the whole day, only at that specific times, it makes me wonder if it have something to do with the date change and dust in the movement? i know i cannot solve this by myself, but it would be nice to know whats causing this issue. Thanks in advance for your replies
