What people say

Owners + reviewers, side by side

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

Oak & Oscar The Humboldt GMT SAR Edition

Oak & Oscar The Humboldt GMT SAR Edition is praised for its anti-magnetic properties, sandwich lume dial, and overall construction quality for its price point. It features a brushed Grade 5 titanium case, a navy blue sandwich dial with an orange minute track and seconds hand, and a Sellita SW330 movement with a 56-hour power reserve. Minor drawbacks noted include bracelet sizing adjustment and lume brightness. On balance, owners and reviewers rate Oak & Oscar The Humboldt GMT SAR Edition highly for its robust construction and unique dial design at its price point.

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.
