CY0811 Posted January 9, 2008 Report Share Posted January 9, 2008 I have a new fast beat BCE and the rotor swings around very loosely when I move the watch/my wrist...Ive had many 7750's and actually 3 of these exact watches...but this one seems looser. Its not the rotor screw thats loose but the amount of turns. Does in need lub etc? It distracts me a bit since I can feel it gyrating all the time....maybe this is a good thing? Thanks Cy Quote Link to comment Share on other sites More sharing options...

rodwc Posted January 9, 2008 Report Share Posted January 9, 2008 Smee again, Was that the table or the wheel that swings? Quote Link to comment Share on other sites More sharing options...
RWG Technical Posted January 9, 2008 Report Share Posted January 9, 2008 I think your reversing wheel click spring is not working. Many of them are defective, I see it all the time. The reversing wheel isolates the rotor from the mainspring, and the click is what prevents the mainspring from feeding back into the rotor. A simple test is with the watch flat in your palm, wind it slowly, if you feel the rotor spinning, your reversing wheel click is not working. The watch will still run, and will sort of wind automatically, but you will have very low power reverve. The good news is that the click is easy to access and fix. The bad news is that accessing it requires taking the autowinder bridge off the movement, and assembling this part is quite difficult.

CY0811 Posted January 9, 2008 Author Report Share Posted January 9, 2008 So am I manual winding when it is in my palm in regards to "wind it slowly" or am I slightly shaking? I knew something was up whenI received the watch and it wasnt running....all the others had gained power reserve from the trip from China...lol. Thanks The Zigmeister....you are a master and the only option for repairs and mods in my opinion. Quote Link to comment Share on other sites More sharing options...
RWG Technical Posted January 9, 2008 Report Share Posted January 9, 2008 What I want you to do, is to test the click on the reversing wheel by handwinding it. Normally when this click is not working, as you wind it, the rotor will start to spin, until the mainspring click engages into a new tooth on the gear. Wind very slowly, and see what happens... Sorry I wasn't clear in the first post. Let me know... Quote Link to comment Share on other sites More sharing options...
gioarmani Posted January 9, 2008 Report Share Posted January 9, 2008 Do ETAs have this problem frequently as well, or is primarily an Asian/7750 thing? Quote Link to comment Share on other sites More sharing options...
RWG Technical Posted January 9, 2008 Report Share Posted January 9, 2008 Do ETAs have this problem frequently as well, or is primarily an Asian/7750 thing? The ETA could have this problem, but I have not seen it on any ETA 7750's, it's an assembly quality issue with the Asian model. RG Quote Link to comment Share on other sites More sharing options...
HauteHippie Posted January 9, 2008 Report Share Posted January 9, 2008 The first 7753 (ETA) I had did this. The rotor spun so violently non-stop, it could almost move my arm. After a long stay in Canada for unrelated work, it came back to me fixed with me not knowing that that this behavior was abnormal/broken in the first place... Thanks, The Zigmeister!

CY0811 Posted January 9, 2008 Author Report Share Posted January 9, 2008 Well I tried winding it slowly and the rotor didnt spin...the chrono was on though. Ill try it with it off as well. Its like after I spin the rotor/roulette table... it spins for maybe 5-8 seconds longer then the other watches and then sometimes kind of goes back and forth (clockwise to counter clockwise 1/8 of a rotor turn) for a a few seconds...or sometimes I hear it wind at the end.. If I shake it harder (jerky shakes) sometimes it will wind without spinning very much or at all. Ps: I also had a interesting experience with one of my Swiss 7750 watches....after it came back from The Zigmeister it just seemd better all around.....smoother...kept better time...quiter, etc. Thanks for your help Rob Quote Link to comment Share on other sites More sharing options...
Dizzy Posted January 16, 2008 Report Share Posted January 16, 2008 my new Ultimate BCE's Asian Rotor spins very fast and freely and of course doesnt wind the watch at all. I've already sent it back for warranty so i cant try the winding test. I was tempted just to install an ETA7750 but we'll see how this warranty fix works out for now... The movement was faulty from the day i got it. I was too bad, it was otherwise a very good rep. dizz Quote Link to comment Share on other sites More sharing options...
lio126 Posted April 4, 2008 Report Share Posted April 4, 2008 Zyggy .. Is it possible to upgrade the ECB V2 with the A7750 28.8ka the ETA7750? I am thinking of changing to take my perfect Replica Super ... And I am not clear if there are problems of incompatibility ... Please clarify whether it is possible to change the new A7750 a Swiss ATS 7750. Thank you and greetings Quote Link to comment Share on other sites More sharing options...
bwhitesox Posted April 4, 2008 Report Share Posted April 4, 2008 You can swap the Aisan 7750 for the swiss 7750 but it requires some modification as I believe a couple of the hands are too big. There a posts on this subject so a quick search should bring up some answers for you. By the way the ETA 7750 is magic and feels sooo much better than the Asian one so I personally think this would be a good swap for this watch.

Thank you and greetings As long as the watch your swapping the ETA 7750 into has a standard 7750 subdial layout (12-9-6) you can install the ETA in place of the Asian one. The subdial and center seconds hands need to be modified to fit the ETA, but otherwise it's straight forward to do... RG Quote Link to comment Share on other sites More sharing options...
