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
