Shanghai 7's series - model 7220

One of the rarest model of Shanghai 7's series.


It carries the 7's series movement with quick-set date-just function same as swiss watch. It means, pulled out the crown in a half way to have date adjust. Had only found lot "7220-101" has this function and very seldom to find in the second-hand market.

Shanghai 7's series - model SS7

The finial standardlize model of 7's. It could be found both calender and non-calender models of SS7 sharing the same back-case. I would say this is the finial and the latest model of SHW factory made SS7's "Tongji". Since the quick-set date-just system of the preview models, 7221,7621... are so fragile, it turns factory to made a low-tech but more reliable canlandar seting system. Date adjusted by pulling out the watch stem in a halfway, keep turning the minutes hand forward to 12 o'clock and backward to 9 o'clock position to have the date-just.

SS7 case back are very common found in the maket.

Shanghai 7's series - model 7621 calendar date-day

Shanghai "Shuang Li" 7621's

Shuang = double; Li = Calendar
An upgrade version of 7221's. It carries ss7 movement with quick-set date-day function. Calendar setting method is same as 7221's, you have to push the stem all the way to the end by turning the crown up and down to set both DD calendar.

Both 7221's & 7621's can consider as rare model as it's the first model which had quick-set function. Compare with 7221's, 7621's are even rarer as the Shanghai watch company has no longer introduced any date-day watch untill SS8 is lauched. The probability to get a 7621's is 10 times harder than a 7221's. Becuase of their unstable date setting design. This model ended and replaced by a more stable and lower-tech model SS7 (3 hrs up & down calendar setting).
