Help: problem with Asian ETA

[lukko]

Hi guys, I just bought a 16610lv from a TD. It is completely new, but it has a problem in my opinion. I made a video for you to understand. Many times the rotor turns a bit alone, not over the top, but a little. If I use the watch as well as it is I risk ruining it? It is hard to fix it? This problem can cause such problems to the movement? how to fix it?

Thanks in advance in advance



Here is the video of the problem:

Common problem with Asian ETA's. One of the two reversing gears in the autowind module isn't working correctly. Often this can be fixed with a cleaning or if that doesn't work, a replacement with gen ETA parts. It won't hurt anything and your watch will probably run fine while it's on your wrist. The only thing it hurts is the power reserve because as the mainspring becomes tighter wound the rotor has more of an inclination to unwind itself.

Is that one of TC's new LV's? I know he had a batch of movements with that exact problem in the last few months.

Hi mate, thank you for the answer. Then I could groped to fix the problem by my hands? Or I risk of damage? (I have a lot of manual hand work). However no, this is a 16610LV LF factory, taken by Ryan (intime.co) for $ 188 TC LV is aesthetically much better than this, but for this price this watch is very nice

This thread will show you exactly how it comes apart and the two wheels, the reversing wheel and the auxiliary reversing wheel. You can try cleaning them but unless you have a sonic cleaner it probably won't do any good. I'd buy a new set of two ETA genuine parts. Then it will eliminate the problem for good. It's a relatively simple fix and easy if you have a couple of small watch sized screwdrivers. Just remember the two wheel look very similar but they aren't interchangeable so remember how it goes back together.

I have done, these two wheels on the left are the private parts right? I try to disassemble, clean, reassemble, realign and see if anything has changed

 

[lukko]

I have just finished, I took off the wheels reassembling everything ... a screw was not close, but despite this, nothing has changed

Some time cleaning works. Sometimes only changing the wheels will fix it.

Those parts are from a 7750, not a 28XX movement.

Ssteel my problem is on 1480 and 1530 wheels right? Thoose parts are interchangeable in 2824 and 2836?

Many thanks

Oops! Good eye Mickey.

And that's correct Lukko, They are interchangeable.

Thank you KBH! where to find these wheels at a good price? replacing these wheels the problem solves at 100%?

 

[KBH]

In EU I would suggest Cousins UK but I'm in US so maybe SSteel can help you there.

And yes, in theory, it should 100% solve the problem unless there's something I'm missing. I'm certainly not a practicing watch smith but I can't think of anything else that would cause that behavior

In any case thanks for your help I've just contacted the TD to ask if he can find and than send me these two wheels, this should be a lower cost for him and for me, compared to that ship back the watch in China for repair.. thanks again!

 

[KBH]

I was going to suggest trying to get the parts from your TD but I've not heard of TD's sourcing movement parts in the past.

Or, if he can't find them, maybe he could ship you a complete autowind module.

Many thanks mate! I will contact the TD and then update this topic ... Many many thanks for now

Ofrei's in the US carries these parts
