Double Rhomb NOS 70ies Handwind with Chinese markings

The Finish might not be compared to a fine Swiss Watch
but the wheels are nicely cut and the screws are classes better then on the movement for the domestic market. Also quite interesting is the large diameter of the balance wheel. I guess the frequency should be 21'600 bph given that size.
If you think that finish is not that great, have a look at this Seiko 7S26A movement of one of my Seiko 5's ("See Through" Edition 2002, Asian Model, Railroad-like dial). Now you see, the finish on those Seikos is a lot coarser. And this movement has been produced with a lot more hi-tech :-)
