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.

Sartory Billard SB04

Owners widely praise the Sartory Billard SB04 for its stunning, custom dials with remarkable texture and light play, with many calling it a masterpiece. The watch is noted for its modern wearing experience and comfortable, light feel, particularly when constructed from titanium. Some owners find the steel casebacks slightly sharp due to deep laser cutting, and one owner notes the hands can be difficult to see depending on the viewing angle. The Sartory Billard SB04 is powered by the La Joux-Perret G100 automatic movement. Overall, owners rate the Sartory Billard SB04 highly for its exceptional dial artistry and perceived value.

From video reviewers

The dial's textured finish and color shift are highlighted as a key strength. The bracelet's perceived lack of refinement and end-link fit are noted as a drawback. Reviewers disagree on the case size, with mentions of 35.9mm and 40mm.
