What people say

Owners + reviewers, side by side

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

Astor + Banks Sea Ranger M2

The Astor + Banks Sea Ranger M2 is widely praised for its balanced design, excellent legibility, and strong GADA (go-anywhere, do-anything) capabilities, featuring 300m water resistance and a scratch-resistant coating. Reviewers note its comfortable 40mm case size and good lume, though one source describes it as good but not great. The movement is a Sellita SW200 adjusted by the brand, with accuracy reported around ±8 seconds per day. The pre-order price is $650, with a standard price of $850. On balance, reviewers find the Astor + Banks Sea Ranger M2 to be a compelling option due to its functional design and robust specifications.

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.
