The Seiko 6215-7000 is one of the earliest professional dive watches to ever come out of Japan—and it still holds up as a serious sport watch decades later. Originally released in 1967, this 44mm diver was a one-year-only production model that laid the groundwork for Seiko’s entire professional dive line. This example shows signs of honest wear, with visible aging on the crystal and dial, hairline scratches on the case, and a bit of quirk with the date change and winding action. But that’s part of the charm. For vintage collectors chasing true tool watch pedigree, this one’s the real deal.
