For sale is the King Seiko 5621 No-Date men's automatic watch with a stainless steel case. Dial protected by Hardlex crystal. It uses a special No-Date KS mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks at 4hz which gives the second hand a smoother sweep than most other Seikos. The movement was hand assembled and regulated. Case and medallion are in very good condition.
