How to read Seiko Serial #'s

[watchman19]

Okay so I have been wondering how to understand the Serial # on a Seiko,

For Example: 123-456

1- Would this be the Year?

2- Would this be the Month?

3- Is this the dat it was made

456- Is this the production #

I am trying to figure out how many Orange Monsters are out there? Initially are they a limited production?

I know the Yellow Monster is a Limited Edition, but lets face it anyone can put Limited Edition on anything but what matters most is the production numer correct.

I know the 7s26 is the movt but what is the 2084 R 2 could that be a production plant? or dial # or anything else?

partly correct.

the first number is the year (you have to guess the decade; "1" could be 1991, 2001, 2011)
the second is the month -> 1= Jan, 2= Feb, 3=March etc S= Sep, O= Oct, N= Nov, D= Dec)
last four digits = running number of that model
