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.

Spinnaker Dumas Automatic

Owners widely praise the Spinnaker Dumas Automatic for its attractive textured blue dial, applied indices, and well-finished case, noting its comfortable wearability due to a short lug-to-lug distance. Some owners flag the use of mineral crystal instead of sapphire and a bracelet with a learning curve and loose keeper. Overall, owners rate the Spinnaker Dumas Automatic highly for its aesthetics and case finishing at its price point.
