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.

Horage Supersede Dual Time

The Horage Supersede Dual Time is widely praised for its technically impressive, 98% in-house micro-rotor GMT movement, thin 10mm case, and 39.5mm size, along with excellent finishing and a comfortable bracelet. Owners also note its robust 200m water resistance and 904L steel construction. Some reviewers find the GMT sub-dial illegible, and one owner reported a bezel alignment issue requiring repair, while another flagged the date setting as potentially confusing. The $8,000 price point is considered high by some, though others view it as exceptional value for the movement and build quality. On balance, owners and reviewers rate the Horage Supersede Dual Time highly for its innovative micro-rotor GMT movement and high level of finishing at its price point.
