Rare Shanghai 1120 - ZheJiang made Shanghai
Rare ZheJuang made 1120 with old pinyin " 17 Zhan" instead of "17 Zuan"
Both version of ZheJiang made Shanghai - 1120
Due to the massive demanding of Shanghai watches for the people in China on 60's~70's, Shanghai Watch Factory had sent some of its products to its neighbor province ZheJiang to assemble and have further processing. But even now a day, there were still not much collector knew what model it should be or how their look likes. I was only aware until I found this Zhe Jiang Zhi(made) 1120.
A lot of collector still classified these kind of Shanghai watch dials(without ZJZ mark) as the rare A-581 dials, since most vintage watch seller put this dial on A-581 movement and ask for higher price. This JZ Zhi dial would be a good evidence for those collectors who still persist on this identity.

Rare Shanghai A 591 movement
A-591 was a transition or experimental product of A-581's next production of 611 series. The factory modified the 581 movement for non-screw balance or anti-shock unit features. Somehow, may be the accuracy can’t met the factory standard, it stopped its production and that’s why not much of 591 had made.
The prototype which I have, it has a non-screw balance wheel with early type regular index. The balance wheel is so rough; I suspected it was hand made by the factory maker.
