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.
