Notes

The Seiko Ref. 6215-7000 (1967–1968) stands as the brand's first 300-meter professional dive watch and only its second dive watch ever produced. Establishing Seiko's enduring design language, it features an innovative front-loading monobloc case for superior depth resistance alongside an ergonomic crown placed at 4 o'clock. Due to its remarkably brief production and historical importance, the Ref. 6215-7000 is widely considered one of vintage horology's ultimate "grail" timepieces and an extraordinary collector opportunity.
