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.

Wolbrook Skindiver II Professional

Owners widely praise the Wolbrook Skindiver II Professional for its comfortable wearability, long-lasting lume, and attractive dial designs, with some appreciating the quartz accuracy and smooth sweeping second hand. The watch features a 40mm diameter, a well-weighted 120-click unidirectional countdown bezel with a BGW9 lumed triangle, and a shock-resistant HexapleX case architecture. It is powered by either a Miyota 9015 or 8315 movement, with the latter adjusted in France to ±15 seconds per day and offering a 60-hour power reserve. Some owners find the 20mm strap potentially problematic and note it wears like a 42mm watch despite its 40mm case size. One reviewer expressed disappointment in hand color matching, poor lume, bezel wobble, and the watch sitting high on its strap, ultimately not recommending it.
