For sale is my 1974 King Seiko 5621-7022 with hacking, handwinding automatic 28,800 BPH 5621B movement. Service history unknown but running about -10s/day dial up (as with all vintage watches, YMMV).

The 36mm x 41mm case was cleaned and fresh gaskets installed. Mineral crystal upgraded to flat sapphire crystal.

$575 shipped to US only. Payment via Zelle or Venmo. No trades, please. I've had 500+ good transactions on this and other watch forums and eBay feedback is available under the same username (where I've had 2000+ positive transactions). No returns unless the condition of the watch is materially misrepresented.
