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

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.

Zelos GT

The Zelos GT is lauded for its value and bold design, with owners highlighting the cool power reserve meter and superb 3-point micro-adjust bracelet. Some owners find the case and lugs could hug the wrist better, and the bracelet is noted as being quite long, requiring significant link removal for a 7.1-inch wrist. The dark green dial, while inspired by Lamborghini, is described as appearing mostly black. Overall, owners rate the Zelos GT highly for its value and the quality of its bracelet at the price point.
