Could you narrow it down to an 80s year too?
Both Seiko and Citizen have a serial number and calibre number stamped on the back of the watch. If you see the caseback...you can tell the year and month of production (so long as you know roughly the production decade of the particular calibre)
Eg. If a seiko had 7A48-7009 and 458965 on the case back
A quick look at the "Seiko Production date calculator" hosted on this site.

You can enter the 4 digit calibre eg 7A48 and 6 digit serial number 458965 and the calculator would spit out May 1984 for that particular watch.
So for a seiko. I would look at lots of watches and find something you like and plug the details into the production date calculator.
A hint is...for seikos the second digit of the serial number will be 4 - April or 5 - May so that should help. (The first digit is year...but not helpful unless you know when the calibre was made) but if you were chasing April or May 1983 for example.. a serial number of 34xxxx for April or 35xxxx for May would be something to chase. We can help with calibres made in the 80s like Automatics such as 6309, 7002, 7009 or quartz like 7123, 8123 H5xx and so many more.
For Citizen....serial number is sometimes longer than 6 digits and I am unaware of a calculator but the serial number uses same structure again....the first digit is year but the second AND third digits give you the month. So a serial number of 304xxxx would give you April 1983 and 305xxxx would give you May. (311xxxx would be November)
(This only works if you know the decade your watch was made)
Hope this isnt too techical.
