The Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition features a 40mm case, 300m water resistance, and a 72-hour power reserve from the Calibre 6R55 movement, distinguished by a grey bezel insert and a wave-patterned silvery-white dial. The clasp includes an improved diving suit extension. Owners note the MarineMaster case is comfortable and wearable. However, some owners criticize the 6R54 movement's accuracy, reporting deviations of +25/-15 seconds per day, and find the production number too large for a "limited" edition, deeming it too expensive. On balance, owners rate the Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition positively for its comfortable case and attractive dial, despite concerns regarding its price and movement accuracy.

Owners widely praise the Seiko Prospex Sea Save the Ocean Special Edition for its exceptional and captivating dial designs, often described as a highlight that evokes ocean surfaces with unique textures and color gradients. The watch is frequently noted for its excellent value, with some reviewers comparing its aesthetics to much higher-priced brands. Owners report satisfactory lume and accurate timekeeping, with figures ranging from +5 seconds per day to more precise results. However, some owners and reviewers point to the bracelet clasp as a point of criticism, describing it as underwhelming or flimsy, and some find the watch to be top-heavy. There are also mentions of imperfect day/date wheel alignment and occasional bezel alignment issues on some models within the line. The Seiko Prospex Sea Save the Ocean Special Edition is available in various case sizes, with some owners questioning if certain dimensions are too bulky for daily wear.
