The watch's large size is polarizing, with some finding it niche and potentially too large for smaller wrists, while others appreciate its unique design elements and consider it Rolex's most serious workhorse. On balance, owners and reviewers rate the Rolex Deepsea highly for its impressive engineering and robust build, despite its polarizing size.

Overall, owners and reviewers rate the Seiko Prospex Sea highly for its classic design and robust build at an accessible price.
