This is a green dial Dongfeng watch. Dongfeng movement signed with ST5 is a fast beater 21600bph and whereas the one signed with "东风” is a lower beat movement 18000bph. This is the second fast beat Dongfeng in my collection. They are exactly the same except that this Dongfeng is a black dial with green color at the centre. However, unlike the first Dongfeng, there is no anti-magnetic shield inside; not sure whether it has been lost before reaching my hands or has not been included originally.
