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 S456 GMT

Owners widely praise the Sugess Seestern S456 GMT for its excellent case finishing, deep blue sunburst dial, and crisp indices, with one owner rating the overall fit and finish 9.5 out of 10. The watch is noted for its legibility, strong lume that lasts about 4 hours, and accurate timekeeping around -4 seconds per day, with easy GMT hand adjustment. Some owners report issues with a loose or friction-based unidirectional bezel, while others find theirs tight and prefer a bidirectional GMT bezel. The sapphire crystal is described as clear and flat by some, but others find it very reflective with AR coating that could be improved. Sizing is generally considered good at 39mm with a 46mm lug-to-lug and 12mm thickness, though one owner expresses concern about its 49mm lug-to-lug and 41mm bezel diameter. Overall, owners rate the Sugess Seestern S456 GMT highly for its impressive finishing and dial at its price point.

Yema Rallygraf Meca-Quartz

Owners widely praise the Yema Rallygraf Meca-Quartz for its heritage reissue design, small and thin case, and good looks for the price, with some noting exceptional build quality, tactile pushers, and a substantial feel. However, the quartz movement's ticking smoothness and the 24-hour subdial, which functions as an AM/PM indicator rather than a totalizer, are points of criticism for some, leading to perceptions of it being overpriced. Owners report mixed experiences with quality control, with some noting alignment issues, crooked indices, and dial rotation when pushers are depressed, while others report no such issues. On balance, owners appreciate the Yema Rallygraf Meca-Quartz for its distinctive vintage styling and wearability, despite some concerns regarding quality control and the functionality of its subdial.
