Some owners find the 43mm case size substantial, with one noting it felt big, thick, and heavy on a 6.5-inch wrist, though others consider it a perfect size. The movement's power reserve is noted as less than newer variants by one reviewer. Overall, owners and reviewers rate the Seiko Prospex Sea highly for its classic design and robust build at an accessible price.
