Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition

The Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition is widely praised for its excellent quality and finishing relative to its price point, featuring a beautiful case, bracelet, and strong Lumibrite lume. Enthusiasts and reviewers highlight the comfortable 42mm case size and the distinctive 4 o'clock crown position. The watch is powered by the in-house 6R54 automatic movement, offering a 72-hour power reserve and rated accuracy of -5/+10 seconds per day, though one source notes the GMT function is secondary.
