What people say

Owners + reviewers, side by side

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

Lorier Hydra SIII

Owners and reviewers praise the Lorier Hydra SIII for its value, GMT functionality via the Miyota 9075 movement, and classic travel-diver aesthetics. Some reviewers note the finishing is simple or a tad rough around the edges, while others find it good for the price. Accuracy figures range from +7 to +8.5 seconds per day. The domed Hesalite crystal may exhibit distortion. Overall, owners and reviewers rate the Lorier Hydra SIII highly for its feature set and value proposition in a travel-diver format.

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.
