What people say

Owners + reviewers, side by side

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

Lum-Tec Solar Marine

Lum-Tec Solar Marine owners praise its all-black diver design, excellent lume, and rugged, tank-like build. One owner finds it a perfect fit for a 7-inch wrist and the most frequently worn watch despite its smaller size. However, one owner cautions that the PVD coating will wear and chip within a year, impacting its appearance, and another finds the price high for a solar quartz watch with added lume. On balance, owners rate the Lum-Tec Solar Marine highly for its robust design and excellent lume, despite concerns about PVD durability and value proposition.

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.
