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 Fleuss GMT

Owners widely praise the Spinnaker Fleuss GMT for its aesthetic appeal, comfortable and light wearability, and value, especially when discounted. The textured blue dial, applied lumed markers, and sapphire crystal with AR coating are highlighted as stunning features. Owners also note the dial is very well lumed and the bracelet has helpful quick-release tabs. However, the 43.3mm case size is criticized by some as being too large, and the Beads of Rice bracelet is described as "jingly jangly" with a pressed clasp and a clasp that isn't finely finished. Some users flag the internal bezel rotates too easily. Overall, owners rate the Spinnaker Fleuss GMT highly for its aesthetic success and value at its affordable price point.
