What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Horage Supersede Dual Time

The Horage Supersede Dual Time is widely praised for its technically impressive, 98% in-house micro-rotor GMT movement, thin 10mm case, and 39.5mm size, along with excellent finishing and a comfortable bracelet. Owners also note its robust 200m water resistance and 904L steel construction. Some reviewers find the GMT sub-dial illegible, and one owner reported a bezel alignment issue requiring repair, while another flagged the date setting as potentially confusing. The $8,000 price point is considered high by some, though others view it as exceptional value for the movement and build quality. On balance, owners and reviewers rate the Horage Supersede Dual Time highly for its innovative micro-rotor GMT movement and high level of finishing at its price point.
