Up for sale a seiko 6139-600x case (including case back / from Jan. 1974).
Case is in good state and has been refurbished. No dent, almost no scratch. The only complain I would have is the left side has been a bit too much polished and the lower edge is not that sharp.
Case will be shipped by registered mail and can be paypal'd.
Asking 35$ all included (shipping + paypal fees).
