Seiko's day-date automatic caliber and the in-house branded version of the NH36 with stricter quality control and finishing. The additional day wheel over the 4R35 adds the day-of-week complication without changing the movement dimensions. Found extensively in the Seiko 5 Sports and Prospex lines, it offers Seiko's proven reliability with the convenience of day-date display at a mainstream 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.
