For sale or Trade: Vintage Seiko 6309 Diver watch from 1979. I bought it here on this forum a couple of years ago. Seller told me it was all original. Bezel turns solidly, crown screws down, crystal is good with a few light marks, lume has gray patina, keeps good time although I have never had it opened up so service history is unknown and comes on Seiko straight vent strap. Asking 170.00 shipped in the U.S. or would like to possibly trade toward a Seiko 6105 plus cash from me or a newer Aqualand JP 2000/2004, or an Ecozilla. Open to offers as well.
