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.

Boldr Safari

Owners widely praise the Boldr Safari for its attractive dials, robust build with 200 meters of water resistance, and reliable Seiko movements. The California dial design is a frequent highlight, as is the strong lume. Some owners note the GMT variant offers full GMT functionality, while others point out the movement's date-only nature on certain models leads to a vestigial crown position. The animal artwork on the display caseback is a point of contention, with some finding it detracts from the view of the movement. Overall, owners rate the Boldr Safari highly for its value and distinctive design elements.
