What people say

Owners + reviewers, side by side

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

Sternglas Naos Pro Automatik

The Sternglas Naos Pro Automatik is praised for its slim 9mm case and Bauhaus dial design, featuring clear hour markers and a framed date window. Owners note the upgraded Miyota 9015 movement with a 4Hz beat rate. Accuracy is reported as -10/+30 seconds per day, which is not ideal for precision enthusiasts. The five-link bracelet's lack of fitted end-links and the optional bracelet's chunkiness are flagged as areas lacking refinement. Overall, reviewers highlight the Sternglas Naos Pro Automatik's improved wearability and premium feel at its price point.

From video reviewers

The Bauhaus design is a strength. The value proposition is a weakness.

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.
