1983 Seiko 5, 7009-876A

[wotsch]

Hello Seiko fans!

I'd like to add a short review of a 1980s Seiko 5. It's in very good condition, on a stainless steel strap and has a blue, iridescent face divided into two rings that reflect differently under different light.

After some internet research, I have found out a few details (links to sources below). Please let me know if I've got anything wrong:

• it was produced in April 1983
• it has a caliber 7009 day/date movement, 17 jewels, 21600 Bph - this caliber was used in Seiko 5s from 1980 until it was replaced by the 7S26 in the late 80s
• the day is changed by pushing the crown in
• the day is bi-lingual. That means it is in both English and German, with e.g. the German version being jumped over at every change
• the watch is 37mm wide and 11mm thick
• it has metal day and date rings. After around 1990, the rings in Seiko 5s are plastic. This helped me work out the decade of production
• a Seiko serial number tells one the year and month of production: the first digit shows the year (without the decade) and the second shows the month. The decade needs to be found out from other indicators (see, for example, the bit about the metal day and date rings above or the information about when the caliber was used)
• the model number stamped on the watch back is in the for XXXX-YYYY where XXXX is the caliber and YYYY denotes the watch body. For this watch, its 7009-876A
• by the 6 on the watch face (see the first picture, very small) are two numbers: XXXX (left) and ZZ ZZ Z Z (right). Again, XXXX indicates the caliber whereas ZZ ZZ Z Z denotes the watch face itself. For this watch, its 7009 83 MR R 2
