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-E

Owners widely praise the Sartory Billard SB04-E for its impressive and deep dials, with specific mentions of the 12 Soleil pattern and the Exquisite Blue Guilloché appearing to move like water in the light. Reviewers highlight its sensible 39.5mm size and 100m water resistance, noting the overall composition looks more expensive than its price. One owner points out slightly sharp edges on the caseback and suggests a more domed crystal. The watch utilizes the La Joux-Perret G101 automatic movement with a 68-hour power reserve. Overall, owners and reviewers rate the Sartory Billard SB04-E highly for its unique dial work and value proposition.
