What people say

Owners + reviewers, side by side

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

Seestern S456 GMT

Owners widely praise the Seestern S456 GMT for its exceptional value and finishing that exceeds expectations, with one owner noting its accuracy surpasses that of their Seiko 5. The dial displays a pearl-like rainbow effect. Some owners would prefer a bidirectional bezel over the current unidirectional one. The Seestern S456 GMT features an NH34 movement, a 39.5mm case, sapphire crystal, and an adjustable clasp. On balance, owners rate the Seestern S456 GMT highly for its impressive finishing and value proposition at its price point.

From video reviewers

The watch features stunning, detailed finishing that is difficult to top. Reviewers did not reach a consensus on any weaknesses.

Spinnaker Tesei Mille Metri GMT

The Spinnaker Fleuss Midnight Black features a reliable and accurate Japanese TMI NH35 Automatic Movement with 3 Hands and Date. A potential drawback is the watch's relatively low 15 ATM water-resistance rating compared to other watches in its class. Reviewers disagree on the watch's suitability for larger wrists, with one reviewer noting a 43mm diameter and 51mm lug-to-lug fit, while the other mentions a 51mm lug-to-lug measurement.
