Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited EditionvsTissot Seastar 2000

The Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition is praised for its compact 40mm case and the new Caliber 6R55 movement offering a 72-hour power reserve. Owners and reviewers highlight the stunning dials as a strong suit for Seiko. However, the 6R movement's accuracy is a point of disappointment for some, who wish for improvements closer to other movements, though others accept it given the excellent overall package. Press images suggest the bracelet end links may appear disjointed. Overall, owners and reviewers rate the Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition well, with the stunning dials and improved power reserve being the biggest reasons.

Owners widely praise the Tissot Seastar 2000 for its impressive specifications at its price point, including an 80-hour power reserve, ISO 6425 certification, sapphire crystal, ceramic bezel, and 600m water resistance, with its dial quality and finishing considered superior for its class. The blue dial is frequently highlighted as particularly sharp and legible. However, the watch's substantial size and weight are consistent drawbacks; its 46mm width, 16.3mm thickness, and 52mm lug-to-lug dimension make it too large for some for everyday wear, with a rubber strap often recommended over the metal bracelet for comfort. A significant concern raised by multiple owners is the bezel's tendency to become loose and lose its click, with one reporting this on two separate watches. Accuracy figures vary, with one owner noting +1 second per day and another around +5 seconds per day.
