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.

Loresum LS05

Owners widely praise the Loresum LS05 for its elegant dial execution, particularly the aventurine and Great Wave designs, and its attractive dimensions, including a thin profile. The moonphase complication is a significant draw, with many finding it a compelling feature at its price point, and the overall finishing is considered well done. However, some owners find the watch too dressy for everyday wear, and the included strap is noted as being of low quality. One owner reported excellent customer service for a repair. The Miyota 9015 movement is standard, with its moonphase cycle drifting over time and reversing lunar waxing/waning. On balance, owners rate the Loresum LS05 highly for its visually striking dials and value proposition, especially for its moonphase complication.
