Hok Posted November 3, 2011 Report Share Posted November 3, 2011 Hello, I recently bought a new, gen Eta 2824 for a seamaster project. I swapped the date wheel. Switching the date manually does work, however it doesn't work when I try to change the date by advancing the time 24 hours in time setting mode. Sadly, I didn't check if date change worked before I swapped the date wheel. I used the easy swapping technique, where you don't have to dissassemble anything. Could it still be that I did something wrong? Is there any reason that a uninstalled movement (with no hands attached) would not advance the date? did I buy a faulty item? thank you for your advice.

kbh Posted November 3, 2011 Report Share Posted November 3, 2011 When you change it by the stem does it kind of snap from one date to the next or is it kind of sloppy? The most likely cause if it's sloppy is that the date wheel is sitting on top of the click spring instead of the click spring being in between the teeth on the date wheel. The spring is roughly at 4 on the dial and if it's not in place the date change mechanism will be sitting under the gear on the date wheel and it won't engage. Changing the date by the stem occurs on the other side of the dial so it wouldn't be affected as much. I hope that makes sense. Quote Link to comment Share on other sites More sharing options...
Hok Posted November 3, 2011 Author Report Share Posted November 3, 2011 Hello kbh, thanks for your answer, I think I am getting what you mean the manual change feels normal. if we say the stem is at 3oclock: the gear at 4 oclock is working correctly. also, the spring at 9 oclock is correctly between the teeth (took me a bit until I figured that one out). Both are positioned exactly like on this picture http://www.chronometrie.com/eta2824/images/eta2824d.jpg Quote Link to comment Share on other sites More sharing options...
kbh Posted November 3, 2011 Report Share Posted November 3, 2011 Then the only suggestion I have it to take the DW back off and watch to see that the date change mechanism is doing when you wind the date over. It should slowly go round and become spring wound right before snapping over at 12. It's the thing with the brass gear towards the bottom with a silver octopus sticking out. As that goes around the leg sticking up snaps the date over. The silver rectangular kind of piece to the right has the click spring attached that should be between the date wheel gears.

kbh Posted November 3, 2011 Report Share Posted November 3, 2011 actually, I just looked the other picture you just posted and first thing I noticed is the date is out of place and so is the spring. Notice where the date is in relation to the stem. Quote Link to comment Share on other sites More sharing options...
Hok Posted November 3, 2011 Author Report Share Posted November 3, 2011 now that you mention it, the image I posted IS wrong... so, heres my movement. best I could do with my camera http://img72.imageshack.us/img72/2488/dsc03604o.jpg I'm not yet sure if I want to remove the face plates so I can see what the date change mechanism does... but if it has to go to the horologist anyway...

FxrAndy Posted November 3, 2011 Report Share Posted November 3, 2011 I would sujest your problem is with the transfer gear that sits between the canon pin wheel and the date change wheel. Quote Link to comment Share on other sites More sharing options...
kbh Posted November 3, 2011 Report Share Posted November 3, 2011 Yeah, I'm not seeing anything wrong with the DW installation. Time for a professional look see. Quote Link to comment Share on other sites More sharing options...
