Hi all, I have a Seiko 6139-6002 chronograph, bought it brand new some 40 yrs ago, I'm trying to find out if Seiko do a manual for it that I can download, 

can anyone give me  a website I can use please

I have looked and I can't find any download for the user manual. The service manual is easy to obtain in two clicks, but that is of no use whatsoever to you

Now, are you looking for collection purposes, or something is not working as it should on your long owned watch? 

Especially if that is the case, I recommed that you look for a reputable, independent watchmaker to give it a long due service. That will make so it performs as it should, breakers due to constant tiunios use without proper lubrication is avoided, and its full value is preserved.

The link below may help.  Whilst not a 'user guide' it does go through the fault checks with each pusher and its function, so may help your understanding.
