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. Newer leather strap & original KS buckle (these are very pricey). Specs are as follows: * Case width: 36.5 (w/o crown) * Condition: Pre-Owned & Very Good * Original KS Buckle * Lug to lug length: 42mm * Lug spacing: 18mm * Thickness: 9.5mm * Hardlex crystal * Movement: 56XX * Production Year: 1971 * WR rating: None * Aftermarket watch strap and Box * No trades, only selling * Free shipping via USPS within CONUS PRICE to SELL: $650 via Zelle or Venmo Buy with confidence.
