What people say

Owners + reviewers, side by side

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

Christopher Ward C65 Aquitaine Bronze COSC

Owners widely praise the Christopher Ward C65 Aquitaine Bronze COSC for its comfortable wearability, durable case and bezel, and smooth winding action, with one owner finding its case superior to a Tudor's. However, accuracy is a significant concern, with one owner reporting +17 seconds per day. The rubber strap is also noted as lacking refinement, and some suggest design tweaks for greater brand uniqueness. Overall, owners rate the Christopher Ward C65 Aquitaine Bronze COSC highly for its wearability and case finishing, despite accuracy concerns with the Sellita SW330-2 movement.

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.
