You are right master The Zigmeister, not all people has the chance (and the skill) to have and use a lathe and this operation could be really different difficult when you see the size of the Reversing Wheel and the price for the ETA part is really expensive ... I don't understand why factory does not sell spare parts of their A7750 especially the parts we cannot find ... Someone, someday should try to get this wheel as it becoming really common' these days I received 5 watches with this problem and had a very hard discussion with my seller because he said that I was lying to him until I sent one day a video with an explaination on how I fixed the problem ... I repaired 2 of them and sent back the rest because of the lack of spare parts...

Fantastic info very useful Thank you so much

I have to add to my tips up Then after all that cleaning, re-assemble all the stuff back and watch out for the rodico don't leave some of it under the bridge when you put it back. Remove the rodico, you will certainly leave some first then you will get the tricks

Finally Francisco the tutorial Thank you very much ! I can add some stuff, I had many problem using this method indeed the reversing was still gummed up and I put it OneDip and MAGIC everything works after that Francisco gave me the idea of that and it was a nice idea as OneDip add a sort thin "moisture" protection... Francisco i posted a question somewhere but I found no answer for it: The ETA reversing wheel has to be cut down as pivot is too big but I noticed that the ETA Bridge is not really different from the Asian wheel but the whole (jeweled) that hold the reversing wheel pivot which is much bigger... Do you think by adding a new ETA bridge the ETA reversing could fit ? that could be a nice thing to try Because I already asked all my connection for reversing wheel parts and it is not possible to get an Asian one, you need to order the whole movement the one who is going to sell one day reversing wheel will certainly earn a lot of money, I would buy 20 of theses ! This topic has to be pinned Something I could add in order to help for the noob like me correct me if I'm wrong You can get rid of tilting pinion assembling using this method but you have to be really precise Remove the rotor Remove the clutch spring Remove the Hammer spring Then put rodico just near the bridge in order to hold down the clutch (use high end rodico as you don't want to leave some rest when you will remove it) then you can remove very carrefully the bridge and you will have have your clutch hold by rodico Something I must add I cleaned the bridge too in order to make it worked ! After all that if it's not working then send back your watch as I have with one of mine no reversing wheel left... Cleaning/lubrificate worked for on 2 of 3 non working watches

I will try the OneDip Method because I'm quite sure that I correctly assembled everything, put the right oil in the right place put the good quantity of oil with special oil stick as well nicely clean the stuff with a special proper cleaning solution (that stinks hell, lol) But I'm sure that the Reversing Wheel is really stucked and I have to try to find a trick to make it smoothed like hell I ordered the OneDIp have to wait for it to test this method ... Thank you for your nice advices Freddy

thx Freddy for the heads up, your advice are always welcomed Yes I disassemble, clean and lubricate (with the correct oil/ 9010 moebius and D5) the entire auto-wind module but not the bridge (which I did it last time I had problem with another movement) :/ Do you thing I have to oil the Rerversing Wheel as usually it's not oiled (treated ETA) where and which oil I would have to use ?... For the rest, yes the RW is installed in the correct direction. (the very flat side down the side without the circled hole) What do you mean by test the module to be sure all wheels spin before reinstalling it onto movement ( because I test that but with the bridge assembled and yes all the wheel are free spinning (Reversing wheel, Reduction wheel, Ratchet and drinving wheel) and the click spring is correctly placed engaged in the RW (no back wheel of the rotor after wind,...) Could you precise your method, do you want me to test it before placing back the bridge or something else ? Something I can tell you is I swapped for another Reversing wheel on another watch and it suddenly worked ... I changed back and was same problem again ... Don't know if it's was only a chance because I correctly installed it or if my Reversing wheel was totally broken or fullfiled by dirt (I'm still not able to clean)... Have you ever experience this problem and fix it by clean/oil auto-wind module and with success ? Next time I'll try something else: 1- Clean 20min Reversing Wheel, Rotor Gear, Reduction wheel and the bridge in ultrasonic 2- Put Reversing wheel in OneDip solution to clean it and give it a very thin "protection lubrificate" 3- Oil and reassemble everything back

The ETA should fit but you will have to give a try ... you can order at www.cousinuk.com ( really serious company) If you want to remove it first 1/ Take off the rotor 2/ Take off the very thin and small clutch spring if you don't want to loose it (normally you have to take it off after the hammer but I prefer to do it first) 3/ Take off the hammer spring but without removing the automatic device bridge * use a wood stick (pegwood) or a brass tweeter (or Stainless one ...) and use the very small hole at the very right end to bring it back from the bridge then you will able to take off do it carrefully To install it you have to get everything assembled but rotor and clutch spring Just put the two left hole in their movement feet then slowly bring back the hammer spring to put it under the Automatic bridge with a tweeter or a pegwood You have to do this very carefully and slowly

i dont have it at home but if will try to order of and use it while waiting for a brand new and working reversing wheel coming from a movement that I will order soon Do you think I can order 21600 bph and take the RW from it or I really need to a Reversing wheel from a 28800 bph ? Thank you for the help I was thinking about something else We know that eta reversing wheel does not fit because pivot is too large but does someone try to use eta bridge i noticed that the eta one is like the asian but with a bigger hole ( jeweled) for the rw that could make the tricks ?...

I receive another one with the same problem... Rotor moves when you turn the crown Hehe I think I'm the guy with the world record of turning rotor ... do you think it could come from the extreme cold weather during shipping ...? This time I don't have anymore reversing gear left... So I cannot fix it... I tried to clean the reversing wheel as well as the reduction wheel in an utltrasonic bath for 20 minutes. I re-assembled everything again, precisely oiled but still have the same problem ... rotor moves when I turn the crown Any tips for me to try masters ? Do you think it may come from a reversing click spring too loose ? I checked the spring and it is correctly fitted into the reversing wheel and it make its job when I turn the crown and stop winding ... HELP ! Question: I feel a strange thing when I manually wind the watch as it is not rotating normaly there is a sort of a very small "gap" when I turn the crown... hard to describe that ....lol

I totally agree this video is only good if you want to show the step by step method however there is not adjustments, no checks... as soon as the hammer spring is put nothing is checked ... reversing wheel..click spring... chrono .... etc... watch out if you want to follow only this method ... Someone should post one day a step by step tutorial with pictures that would be nice ! hehe

Thank you for your reply masters ! I fixed my stuff ... here is what I have done ... I dissasembled the first stage of the watch only, took the reversing wheel as well as the reduction wheel... it was filled by dirt... I took those two wheels and the chronograph bridge and put them in a subsonic bath for 3 minutes I reassembled the movement put ETA OIL as described in eta tutorial.... everything was well assemble but the rotor was still moving when I turned the crown ... I dissasembled again and this time I changed the reversing wheel (I noticed it was scratched in the upper left side of it ) with another Asian 7750 reversing which I had from a non working watch ... I reassembled and now everything works, the rotor does not move anymore when you turn the crown... this reversing wheel is quite bad shapped don't know why they have used eta style reversing wheel ... Anyway maybe one last question for you masters... The only problem I still have but it's not really a problem... (Ihave this problem since I received the watch) 1/ I don't hear nicely the click ... click coming from the ratchet wheel and its string ... 2/ There is still some bad friction when you manually turn the crown for winding ... (is it a problem coming from the ratchet wheel or crown wheel or maybe something else... ?) Thank you for your support !

thank you for your input francisco ! I tell you what, that does not smell good ... hope it will change And yes Pt hope you are right

good catch

I confirm also ... He is slow like hell these days around 3-5 days for an answer ... hope he will change that because it is not really fun .... especially when you are in a hurry

This is not true at all ... Eu custom can make random check on every package they want even if it's coming within the EU (and I can tell you something that they make it much often than you could all imagine) don't be so relax with custom they know a lot of thing ...

my friend if you want my opinion you were clearly lucky this time and lucky also that you are not in france, switzerland... because this kind of thing does not work right there... But next time ask for a registered mail delivery... no EMS - NO FEDEX trust me you can still ask for a toy as it will avoid in a certain way postal guys who want to make good christmas gift before christmas but won't compromise customs ... Or another good advice, stick with european dealers that will cut problem to 50% it's not 100% safe but it's a lot more efficient than the China way

keep us inform anyway of your situation

This is absolutlely not true ... It really depends of where you are living !... In certain countries they just destroy the watch, in the other ones you are similar as a dealer ! When you buy a fake, in France and Switzerland where it's a real crime to import and wear this kind of thing you are treated like a dealer... I cannot understand how Andrew can use such bad idea as a Watch in Toy ... for custom they know all the tricks especially in these two last countries... and as it's in europe the word has been passed to other countries... Anyway I don't know what you should do for your custom problelm If you send a false invoice maybe they only want to charge you, as they are aware of the prices ...but you are going to pay a lot of tax for a 5000$ watches !... So maybe sent an invoice with a smaller price such as 1200$ (as it was a used watch) Maybe they just want a prove that you ordered it so they can force you to pay a fines... etc... So in that case, the best is to not anwser or tell them that you did not order such thing and that they can destroy the watch or send it back ! Anyway don't really know what to do ... as it's so different for each country I'm just astonished by such sickness from Andrew sending a watch IN A TOY !! for god sake, I can tell you for sure that they know the tricks !!! I can also tell you something more if they try to do the same in France and switzerland Currently here is a good info ....ALL EMS/FEDEX PACKAGE COMIING FROM CHINA, THAILAND, ... containing sample stuff - low price - are ALL CHECKED !! and especially from GUANGZHOU. They should meditated on that and find a real solution I think that this dealer from China they leave in a dream... they should take some real infos of what is going on from here ... it's good to change host provider but they don't notice that it's too calm ... there is always something hidden in calm situation ... Meditate ...

sad to here that I'm not alone :/

Hello guys, I'm sad... I know that you all know this situation when you receive you watch and you notice that there are filled by mechanics flaws or something else ... So I have to speak here because I feel like I'm the only one having such a problems in the community ! I've just ordered 3 watches from a well known dealer ( won't tell his name as he offered me to replaced them) First one Chrono was not working (he told me that when he QC it) so I got a replacement not the same color but that's ok - GRAHAM I can leave with it Then I received the Porsche FLAT 6 7750. I tried to wind manually the crown it worked but it seems that the movement was not really nicely mounted as the Rotor was moving with the crown turn like a car wheel running at 250 MPH For information rotor does not have to move when you turn the crown Above all, when I moved the date it was filled by dirt ... (I send it back for another one) Then I received the MontBlanc, this time, the rotor was not working ... in fact it was turning inside the watch but free, without any sort of resistance, indeed the wheel that moves inside with the rotor (the small one you can see under a hole) t is not moving with the rotor movement so the rotor is not able to give its power and thus power reserve to the watch. I can onlt manually wind it as a venus one ( I will send it back) sad... sad .... maybe after a long walk together, I will certainly go for another dealer like Eurotimez who seem to really make clear QC or maybe it's just my fate or my bad luck...but damn I'm feeliing really bad... Ilove too much these watches ! lol :/

Yes it works. I already get the same problem as you and changed my A7750 rotor with the ETA one and the horrible noise (rotor touching the case back) is gone. Don't try to tighten the screw too much as the Asian 7750 screws are really fragile. You could break your head screw and possibly block your rotor. Anyway the ETA 7750 Rotor can be placed on the Asian 7750 movement. it worked perfectly for me. The only bad thing is that the 7750 ETA rotor cost a lot of money with all ball bearing, etc... Another thing try to swap another of you A7750 rotor from another watch for instance sometime it works and remove the rotor touching the case back noise...

HEllo guys, I have a problem with my watch but I don't know if it is normal or not When I move the crown the rotor moves too. For the rest everything is ok, the watch is working. The only thing I could say is that I have a poor power reserve Movement 7750 Asian 28 800 BPH on a Porsche COuld someone help me out with this

We can only hope that the lite version of the BB would be well made. Just hope that those Ceramic Bezel Copy would be as nice as the previous one. And let's hope also that they will build all part as the previous one too. But I think this is a good warning for all of them... dealer as factory You cannot sell all this things without taking some very good protection... But the temptation is big and of course they want to sell to lot of people to gain more money and we cannot do that without being hidden... anyway let's way and see

I tell you what I think about that. that does not smell good... at all... Andrew and Josh should worry about that. I can also tell you that the case started now and since some time ago... And if they show up screens it's because everything is now done... :'( not good... not good at all... As you noticed they are not showing pic of some scammer site as they don't care about it. They care about the watch that really look like the gens and this is why they are afraid... and I can tell you that they will spent a lot of money to stop them... They are certainly followig the path to the factories ... they should all be afraid about that ... and take some decision to secure everything

From one of our star dealer but he managed to fix everything for me. He also warned me about the flaws as he QC the watche and asked me if I wanted it anyway. I told him yes as I'm able to fix 7750 movement. He sent the watch to me and I got another one almost free...
