Up for sale is a Seiko Seikomatic Weekdater 6218-8971, often nicknamed the “King Dolphin,” from the mid-1960s—right before Seiko’s move into Grand Seiko automatics. It runs on the robust 6218 automatic movement with 35 jewels, a clear step toward Seiko’s higher-grade mechanical watchmaking of the era.

This example features a clean silver dial with a subtle sunburst-like light play that shifts nicely under different angles. The case has been carefully Sallaz polished, keeping strong lines while restoring its original look. Overall, a well-preserved, honest piece that wears exactly how a high-grade vintage Seiko should.
