This vintage Seiko 4004 is in extremely good condition for its age.  There are some light scratches on the case, band and back.  There are also a few light, hard to see, scratches on the crystal.  It has a new battery and has been keeping good time.  I would recommend that it be service at some point because of its age and would not trust it in water because of the same reason.  The band is a Seiko band, but I don't believe it to be original to this watch.  Please refer to pictures for more information.  Please let me know any questions you might have.
