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 S446 GMT

Owners widely praise the Sugess Seestern S446 GMT for its outstanding finishing and materials at its price point, with specific mentions of the cream or ivory dial, polished hands, and clear crystal offering superb legibility. Accuracy is generally good, with one owner reporting +2/3 seconds per day from the Seiko NH34A movement. Some owners find the lume is not a strong point, and the bracelet clasp could benefit from more micro-adjustment, with screw pins noted as cheap. The GMT hand is described as flat by some, and opinions are split on the "Sugess" versus "Seestern" logo. Overall, owners rate the Sugess Seestern S446 GMT highly for its beautiful dial and excellent build quality for the price.

Yema Diver

One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner notes this manual wind Yema Diver has a cool patina but is unlikely to be waterproof or gain value. Overall, owners view the Yema Diver as a fun second watch rather than an investment.

From video reviewers

The Swiss Sellita movement is a notable feature. Reviewers did not reach a consensus on any weaknesses.
