zzipy Posted November 10, 2011 Report Share Posted November 10, 2011 I got the bug to play with watches movement. Long story, end result I mess up my beloved A7750 panda ebel and am luck enough to find a proper watchsmith, he is not cheap While working on my A7750 Ebel, I messed up my Chrono Second Hand Wheel - this is the stem that rises from chrono mechanism to move the large chrono second hand. I take it to the watchsmith and he replaces it with the Chrono Second wheel from the 2 movements I have been practicing on and I am thinking problem solved. NOPE, the barrel (tube) from the movements I have used for donors is smaller that the Second hand opening, with the result the second hand never sets back to 12 when we reset the chrono. It goes willy-nilly where it wants. He has even tried to see if ETA is compatible, it is not. What are my options, I love my Ebel Panda and want it back to its glory and I swear never to even open the caseback of a A7750. thx Quote Link to comment Share on other sites More sharing options...
maxman Posted November 10, 2011 Report Share Posted November 10, 2011 Lesson learned...you really do have to know what you are doing when It comes to working on movements...especially chrono movements,,,7750 etc. I suggest you try to contact one of the watchmakes/mods here...tell them your problem...and wait for a reply. Best of luck. Mike Quote Link to comment Share on other sites More sharing options...
redwatch Posted November 10, 2011 Report Share Posted November 10, 2011 It is entirely possible that the chrono hand tube has "opened up" as a result of you pulling the hand off of the movement. A capable watch maker should be able to determine that and have the tools necessary to close the tube down. If that is not the case, then I am also pretty certain that the A7750 and swiss ETA 7750 do not have compatible hand sizes (I could be totally wrong on that one, but I seem to recall hearing that somewhere). Where are you located? Perhaps we can suggest a watchsmith for you. Quote Link to comment Share on other sites More sharing options...
zzipy Posted December 20, 2011 Author Report Share Posted December 20, 2011 Sorry for the late reply. Work gets in the way The watchsmith I am working with is pretty competent and showed me the part. It is in bad condition. I have also ordered a pair of hands as I scratched mine pretty bad but our trusted dealers can't source just the chrono second wheel with the tube. I would need someone to donate/sell the chrono second wheel if they have one and hope it fits. I am in Washington,DC area and open to a second opinion if someone can recommend a trusted watchsmith.
