Being fairly new to the world of Seiko, I'm looking for some help please. I have an opportunity to purchase a 6138-0049 supposedly in excellent condition. It's being sold by the original owner with box, sales slip etc. Reason he's selling is his wife bought him a Rolex and since then it's been sitting in the original box. It was apparently used for only 4 years and never been serviced. He's looking at getting about $350.00. How does this sound from you people with more experience than I have? Thanks for any advice you can offer.
