Seller of Asian 7750 movements?

[barkhorn]

Hello to everyone

 

I have two chronographs that need a new caliber. I already know sellers of the Shanghai 3lzf2, but my watches are equipped with the Liaoning (28.800 bph model). Do you know someone with stock of Liaoning calibers to sell? I can´t find nobody with Google.

 

The watches run fine but recently they suffered a hard blow (my fault). Remove the caliber would be the perfect solution because my watchsmith says than some parts are broken and he didn´t know where to get those parts.

 

I could buy the Shanghai 3LZF2  If this one and the Liaoning had interchangeable parts, but I am not sure and I don´t want to buy new hands, crowns, etc. It would be too complex, and I want to maintain the original design of the watches.  Someone with more experience could give me any advice?

 

Thanks in advance for your help.
