otek Posted September 13, 2010 Report Share Posted September 13, 2010 (edited) 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 Edited September 13, 2010 by otek Quote Link to comment Share on other sites More sharing options...
krpster Posted September 13, 2010 Report Share Posted September 13, 2010 Sounds like something caught in the wheel train if it's happening at the same time every day and a manual advance get you passed it. Probably if you are wearing it the motion of the watch on your wrist is enough to push it along. Best bet is a service and all will be good.

otek Posted September 13, 2010 Author Report Share Posted September 13, 2010 Thanks for the fast reply krpster i also do suspect something is stuck somewhere,but the funny thing is it only happens at night, no adjustments needed at any AM time..so i wonder if there is really something that got stuck or other problems to do with it , I will wait and observe for a few more days before i send them out for servicing or repair. Thanks again. Quote Link to comment Share on other sites More sharing options...
krpster Posted September 13, 2010 Report Share Posted September 13, 2010 If in the date change system this could explain the once / 24hr. Hope you are able to work it out. Quote Link to comment Share on other sites More sharing options...
sander Posted September 13, 2010 Report Share Posted September 13, 2010 Are the hands free to pass each other? Quote Link to comment Share on other sites More sharing options...
otek Posted September 13, 2010 Author Report Share Posted September 13, 2010 @krpster Thanks mate, i'll give it a full test tonight and see if its still having issues, but i think there is something that stuck in the wheel train, as i tried to check if all chrono hands would work, i realized that the hour chrono counter hands does not change even after 2 hours of testing the chrono, hope its gonna work out fine. @sander the hands are not touching any parts, as i mentioned 10.50 AM and other times works fine, only when it approaches 10.50PM and will not move until i set it back about 11.20 PM manually Quote Link to comment Share on other sites More sharing options...
geo1nah2a Posted September 13, 2010 Report Share Posted September 13, 2010 The problem is with the date part of the caliber. 10:30PM is roughly the time the slow changing of the date starts. Did you, by any chance, try to set the date (first pull of the crown) with the hands indicating that time? Quote Link to comment Share on other sites More sharing options...
otek Posted September 13, 2010 Author Report Share Posted September 13, 2010 @geo1nah2a I also suspect it have to do with the date change, as far as i remember, i always followed the advice to change the date only at specific times of the day, so i always do it with the hands around 5..anyways, Thanks alot for your input!

txcollector Posted September 13, 2010 Report Share Posted September 13, 2010 try quick change the date a few times and turn the hands manually to change the date as well. If there's something stuck it might get back in place. If not you will need to get someone to fix it for you. It's not an impossible task but you will need tools and some experience to do that.

otek Posted September 14, 2010 Author Report Share Posted September 14, 2010 Thanks alot for your help txcollector i will give them a try later on, as of yesterday i noticed that the min and hour hands does stuck when the auto date change is engaged, i then set the date, as soon as the date changes, it all works fine again..till this morning with correct to the sec. like you mentioned, even though it seems pretty simple, i just dont have the correct tools and experience yet. So, ill be keeping an eye on them for another few days, but id def. need it to be checked properly by a watchsmith. Thanks again mate.

14060 or 16610? Posted September 17, 2010 Report Share Posted September 17, 2010 What you described can occur if the drive gear, date advancing wheel and jumper are dry. Not uncommon for an A7750. That can be cleared up during the course of a service. Quote Link to comment Share on other sites More sharing options...
Jkay Posted September 17, 2010 Report Share Posted September 17, 2010 Ah so there you go. Nice suggestion. It's highly recommended that if you spend the money on a high quality A7750 rep that you get it serviced immediately. No waiting. Quote Link to comment Share on other sites More sharing options...
