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.

Cincinnati Watch Company The Cincinnatus Field Black Automatic

Owners widely praise the Cincinnati Watch Company The Cincinnatus Field Black Automatic as a stunning and well-made watch for the money, highlighting its textured dial, applied gilt numerals, and handset. The 38mm size is considered a comfortable fit, even on larger wrists, and the micro-adjust bracelet is a notable feature. Owners also appreciate the satisfying winding action of the Sellita SW200-2 Power+ movement and the alternating polishing and brushing on the bezel. Some owners, however, dislike the dial design or prefer a glossy black dial over the textured one, and one owner noted the watch comes on a NATO strap only. Overall, owners rate the Cincinnati Watch Company The Cincinnatus Field Black Automatic highly for its value, build quality, and appealing design details at its price point.
