Nanning Watch Factory
From Chinese Watch Industry Wiki
The Nanning Watch Factory was founded in 1970 for the production of the Chinese Standard movement. The factory's main business is the manufacturing of mechanical watch movements, however they also produce their own series of complete watches under the brand name Guihua.
Currently they produce a skeletonized version of the Standard movement in a variety of coloured finishes, as well as their NN28 and NN38 series of movements which appear to be almost identical to the Dixmont-Guangzhou DG28 and DG38 series. Slight differences in the cut of some of the plates indicate that the NN and DG are independently manufactured.
