Nivada Grenchen DepthmastervsSeiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition

Owners widely report terrific build quality and a feel similar to the 1960s original, with some appreciating its reasonable lug-to-lug and better-than-expected appearance in person. The compact 39mm case is praised for its wearability, especially on smaller wrists, and offers impressive 1,000m water resistance. However, the Soprod P024 movement's 38-hour power reserve is a point of criticism, as is a bezel that can be difficult to grip and weak lume. Some owners find the watch wears on the smaller side, and the date complication is seen by one owner as detracting from the design. The "Pacman" variant is noted as polarizing, with one owner questioning their purchase, while the "Ghost Purple" variant's 30 and 45 numerals are described as having a rushed aesthetic. Overall, owners and reviewers rate the Nivada Grenchen Depthmaster highly for its faithful reissue, impressive water resistance, and comfortable wearability at a competitive price.

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.
