  1. Hi all, I broke the pivot of balance wheel on ETA 2804-2. I bought a generic complete balance wheel with bridge for ETA 2824-2 (http://www.ebay.com/itm/262234041099?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and tried to install it without any difficulty. There is only a difference between the new and old one is the shock assemblies (Incabloc vs Novodiac). In the photo below, the new one is the yeallow on the right hand side. My question are: - Is the complete balance wheel and bridge replaceable between those movements? - If Yes, after installed, the balance wheel has swung a little bit then stop. What is the reason? How to fix it? Thank you
  2. HI I know there was another thread that started out with this- but it eventually wandered into polishing a watch/bracelet. Anyway I have two tudor prince. They have eta 2824 inside, but the tudor version- as far as I can tell, there are a few differences- but only on the dial side of the movment- the date jumper, the setting level jumper etc. The real eta is much easier, you dont have the tiny little yoke spring and while there are a few little things to watch for, it almost just goes back together and works without problems. The Tudor version however, is tricky. I cannot seem to get the stem to work right. I can get all of the springs and parts in the right place, and it will work doing some functions, winding, or moving the hands, but maybe the date wheel wont turn. Or the date wheel turns, but the stem comes out, etc. Also I need a date jumper for one of them, does anyone know where these obscure parts are available from? Has anyone had experience getting this to work? Is there a trick to setting the spring, or "forming" (not bending) the spring or some other trick? I want to get this beast back together!! Thank you for your help. I know there have been photo series of this on another site done, but the photos are taken down. I hate to pay 100$ to get this fixed when I can do 99% of it. If I could just get a little advice- I could probably get it done quickly. Thank you in advance. I might do a photo document of the differences in the tudor and eta- would that help anyone?
  3. First I would like to give my many thanks to Mark Lovick for sharing with us all the wonderful world of watch repairing. His talents at the bench are a great source of inspiration and motivation. I have learned great tips on technique. Books are good, but being at the bench with a professional such as Mark is a true joy. His care and dedication shows us all what can be accomplished through patience, determination, and the willingness to learn. Mark, your videos are unmatched anywhere, they are truly a gift. Thanks again. And now on to my main topic. Whilst servicing an ETA 2824-2, I received the new mainspring. Upon examining the inner coil that has the slot for the hook on the arbor, it became obvious this last and important coil was incorrectly formed and way too large to fit the corresponding diameter of the mainspring arbor. The photos show it clearly. I have a question for Mark. Is it somewhat common? Is it just a matter of forming this coil to fit? I have not come across this before. I think that the mainspring should not have to be altered, as this may cause a stress point. I am tempted to return it for another. The mainspring is shown with the corresponding arbor to compare.
