The watch is considered a noticeable step up in general quality compared to other budget brands. One owner purchased an orange variant for around $100. Overall, owners rate the Ratio FreeDiver 200M Automatic highly for its exceptional value at the price point.
The Seiko Prospex Sea Save the Ocean Special Edition is widely praised for its exceptional and unique dial designs, often described as a highlight with wave patterns, lagoon hues, or even manta rays, offering a "Grand Seiko feel" at a regular Seiko price. Owners and reviewers consistently note the attractive color combinations and textured appearances, making it a standout feature. The watch is generally considered solidly built and good value, with satisfactory lume and smooth bezel operation. However, the bracelet and clasp are frequently criticized as underwhelming, rattly, and lacking a convenient diver's extension, a common complaint across several Seiko models. Some owners also express a desire for exhibition casebacks or note potential quality control issues such as misaligned bezels or day/date wheels. Overall, owners and reviewers rate the Seiko Prospex Sea Save the Ocean Special Edition highly for its visually striking and unique dial designs at an accessible price point.
