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 Hass Automatic

The Spinnaker Hass Automatic is a 43mm watch featuring an NH35 movement and sapphire crystal, with owners highlighting its beautiful dial. Some find Spinnaker watches, including this model, to be on the thicker side, with one owner describing the Hass X MCS Blue Fade variant as comically large and chunky. The Spinnaker Hass Automatic was offered at $445 USD as part of a special collection with customized elements, and a limited edition of 200 pieces was also available for $195 shipped. On balance, owners and reviewers note the attractive dial as a key positive, though some express reservations about the watch's thickness.
