Seiko Prospex Sea 1968 Heritage Diver's GMT WatchvsLongines LEGEND DIVER

The Seiko Prospex Sea 1968 Heritage Diver's GMT Watch offers a 300-meter depth rating and a caller-style GMT complication powered by the Caliber 6R54 movement, which provides a 72-hour power reserve. Reviewers note its refined clasp with extensive micro-adjustment. However, the movement's accuracy, ranging from +25 to -15 seconds per day, is considered a drawback by some. Overall, reviewers highlight the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch as a good reminder of Seiko's value, despite the wide accuracy range of its movement.

Owners widely praise the Longines LEGEND DIVER for its faithful retro design, often calling it one of the best vintage reissues, with the 39mm variant lauded for its perfect size and the 42mm for its versatility. The watch is consistently noted as ISO 6425 compliant and powered by the COSC-certified L888.6 movement with a 72-hour power reserve. Reviewers highlight its sophisticated look, clean no-date dial, and the well-made beads-of-rice bracelet, though some owners find the polished center links or overall polished finish dressier than expected for a diver. Owners are split on the 39mm's bracelet, with one finding it too "blingy" and another praising its comfort. The 42mm version's 50mm lug-to-lug measurement is considered long by some, while others find it comfortable. One owner of the 42mm model reported a scratched hour hand after 15 years, and another noted the original leather strap's poor quality.
