This is my Citizen ana-digi temp JG2***, circa 1983 in mint condition and is possible my favourite digital watch in my collection can any one please tell me the year of manufacturer, serial no. 991205.  NB it is the model with the square dials, not round, and i believe is quite rare and desirable.

According to your serial number 1989 September. There are quite a few variants of this model. I recently has a blue faced version.

regards

Adam
