Seiko Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition

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.
