Reviews

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

Gravithin Argomatic - AM01

Owners praise the Gravithin ARGOMATIC - AM01 for its refreshing, clean, and unique design, with particular admiration for the mesmerizing sandwich dial and brilliant execution of BGW9 Super-LumiNova lume. The watch is considered good value, featuring a unique case and meteorite dial. Some owners would have preferred a case size below 40mm, though the brand chose 42mm for case shape reasons. A reviewer regretted the choice of a see-through caseback over an engraved one that would better suit the thematic inspiration. Overall, owners rate the Gravithin ARGOMATIC - AM01 highly for its distinctive dial and lume execution at the price.

Sternglas Naos Pro Automatik

The Sternglas Naos Pro Automatik is praised for its slim, wearable 38mm case with a mix of brushed and polished finishes and a refined Bauhaus dial design. Reviewers note the upgraded Miyota 9015 movement and improved wearability. Some find the optional five-link bracelet too chunky and lacking refinement, with one reviewer noting its accuracy of -10/+30 seconds per day is not for precision enthusiasts. On balance, reviewers rate the Sternglas Naos Pro Automatik highly for its slim case and refined dial design at its price point.

From video reviewers

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