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

The movement is noted as a 6R54 automatic. Overall, owners and reviewers rate the Seiko Prospex Sea highly for its robust construction and classic dive watch aesthetics at a fair price.
