The 21 jewel 8200 automatic movement (21,600 bph) was first produced around 1975, and by the end of the 1970s it had become Citizen’s standard automatic, as the range of mechanical watches was massively reduced as a result of the quartz revolution. Although the majority of 8200’s you’ll see are 21 jewels, they were also made with 17 jewels – I don’t think that version was used in the Eagle 7 line though. Although I include the 8200 in the Movement Table, it was one of the latest movements to be produced in the time frame I have researched, and I don’t (as yet at least) have an example in my collection. However, it is an important movement since it became the Citizen’s base auto for many years, used in a great number of models up to the present day, especially the ‘Eagle 7’ line which rivalled the Seiko 5. These watches regularly show up for sale, and other than the diver models they don’t make a great deal of money. However, in good condition they should be reliable and accurate watches.
I recently had a question from ‘Kurtnet’ (see here: https://sweep-hand.org/movement-table/#comment-1882) and he sent me pics of his watch to help check it out – he was worried it might not be authentic. It looks correct to me, and since it is not marked ‘Eagle 7’ I think this is one of the earlier ones. This one has a serial number starting ‘901’ so I think it’s from January 1979. I thought it would be nice to show the pics here:
Kurtnet’s watch is in decent condition, the case has not been polished and retains its sharp edges. Some scratching on the glass, but it has a nice hand set, and also has Kanji days:
Thanks for the photos Kurtnet 🙂
