dutchguy2 Posted May 20, 2013 Report Share Posted May 20, 2013 I have one but the GMT hand does not move. If I change the GMT hand by hand it all works but as soon it has to move automatic it stops after 5 mins while the rest keeps moving.Any one know where the problem is?

docthor Posted May 20, 2013 Report Share Posted May 20, 2013 Sorry...I can't help but I had the same problem with my latest purchase from Andrew a 16750.Asked him what to do he replied it's a known bug, I should send it back to him he'll replace it.Well...I decided to sell it with a little loss since I don't have the patience to wait and since there is another pepsi to come Domi said that there is a problem with the movement but he can fix it So at least it shouldn't be that serious Sent from my wooden drums using Tupperware.

tr573 Posted May 20, 2013 Report Share Posted May 20, 2013 After you set the gmt and time, try going back to position 2 on the crown and setting the date. So make sure you set date last basically - see if that helps. If it doesn't it may also just be that they left out the dial washer or that it needs a little more bend in it to keep friction on that Gmt hand gearSent from my DROID RAZR using Tapatalk 2 1 Quote Link to comment Share on other sites More sharing options...
dutchguy2 Posted May 20, 2013 Author Report Share Posted May 20, 2013 Thans guys. Just took it all apart and when without a dial and other hands besides the GMT hand it runs. I just put a more bent washer in to see if that solves the problem. Quote Link to comment Share on other sites More sharing options...
cjjoyce1 Posted May 20, 2013 Report Share Posted May 20, 2013 Before you took it apart, when you moved the GMT hand, did it jump hour to hour or move like a normal hour/minute hand? If it didn't jump, the gear wasn't seated properly. Hopefully, your bending the washer will solve it. Quote Link to comment Share on other sites More sharing options...
JoeyB Posted May 20, 2013 Report Share Posted May 20, 2013 Keep in mind that the ETA conversion to GMT, ETA 2836-2/2846, is a modification, and never was a factory design. An extra hand is being squezed in there, and extra gears. Sometimes it needs a little help to get it working right. Quote Link to comment Share on other sites More sharing options...
dutchguy2 Posted May 20, 2013 Author Report Share Posted May 20, 2013 Got it working now. Indeed the gear did not sit properly.Thanks for all your advice. Quote Link to comment Share on other sites More sharing options...

JoeyB Posted May 20, 2013 Report Share Posted May 20, 2013 great...I wish I had your skills Sent from my wooden drums using Tupperware. You do. If I can do it anyone can. I have old eyes that need a lot of help seeing small parts, big fingers and hands that were never used for 'fine' work. If you are a physician, then it'd be easier AND you gor a lot of the tools that are better quality than what we use. There are tutorials on most all repairs on this site, step-by-step that are great. That's the knowledge needed. All I needed then was the guts to try it. I figured the worst that could happen was that I ruined a movement and would have to pay someone to fix it. Instead it worked, much to my surprise and delight, and I've gone on to learn other repairs. I really encourage people to try it, because I really mean that if I can, with no talent, anyone can!

conx Posted May 20, 2013 Report Share Posted May 20, 2013 This is a common 'feature' of the 2836 GMT conversion. The GMT hand 'slips' and loses sync with the hour and minute hand. There is a really easy fix to get it back working again without dismantling the watch. It's not permanent but it will work for a while.Adjust the GMT hand to where you want it, relative to your hour hand.Then set your time and scroll through a day or so.Just turn the crown and advance the time for 24 or 48 hours. It will get the gears back in synch and you should see the GMT hand working perfectly while you scroll through your time. It should work for a while.Whenever mine would slip out of synch that little trick would usually get it back working again. 1 Quote Link to comment Share on other sites More sharing options...
sneed12 Posted May 21, 2013 Report Share Posted May 21, 2013 I have one but the GMT hand does not move. If I change the GMT hand by hand it all works but as soon it has to move automatic it stops after 5 mins while the rest keeps moving. Any one know where the problem is? You've addressed the major potential problems... the only thing left is if the gear itself is slipping, and the only way to fix it that I know if is to glue it and remove the independent setting functionality (or replace it with another).

FxrAndy Posted May 22, 2013 Report Share Posted May 22, 2013 If you find that the gmt gear is slipping then it can be cleaned and the a small drop of D5 will normally provide the sticktion needed Quote Link to comment Share on other sites More sharing options...
