What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Seiko 62MAS

The Seiko Prospex Sea 1965 Heritage Diver's Watch is praised for its vintage-inspired finishing, crisp bezel action, and build quality. Owners widely report the movement averages within +/- 10 seconds per day, though some note accuracy issues. The 40mm case size is considered by some to wear larger than expected, and the price point is a subject of debate, with some finding it too high and others fair. The watch features a 72-hour power reserve from the Caliber 6R55 movement, a 300-meter depth rating, and a box-shaped sapphire crystal. On balance, owners and reviewers appreciate the Seiko Prospex Sea 1965 Heritage Diver's Watch for its refined design and solid build quality, despite some reservations about its price and perceived size.

Seiko Prospex Sea 1968 Heritage Diver's GMT Watch

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.
