What people say

Owners + reviewers, side by side

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

Sugess Seestern S430 Titanium Diver

Owners widely praise the Sugess Seestern S430 Titanium Diver for its genuine titanium construction, making it extremely light and comfortable at 92 grams on a 6.7-inch wrist. The ceramic bezel is described as fantastic and mesmerizing to use, and the brushed finishing is noted as nice. The watch features an NH38 movement, which is appreciated for its lack of ghost date functionality. However, some owners find the price comparable to competitors and have noted issues with the clasp's fit, with some finding the existing holes insufficient and the rotating arm needing to bend. The crown unscrewing is not smooth, and the bezel action is described as gritty with uneven resistance. One owner reported a crown tube failure on a V1 model. Overall, owners rate the Sugess Seestern S430 Titanium Diver highly for its lightweight titanium build and excellent ceramic bezel, despite some concerns regarding the clasp design.

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.
