Miyota
Miyota's premium automatic caliber positioned as a Japanese alternative to the ETA 2824-2 and Sellita SW200-1. The 9015 adds hacking, hand-winding, and a smoother 28,800 vph beat rate over the budget 8215. Its thinner profile and higher jewel count make it a favorite among microbrands seeking a reliable mid-range movement that punches above its price point.

The community take
Owners talk.
Owners widely praise the Gravithin ARGOMATIC - AM01's refreshing, clean, and unique design, with reviewers specifically highlighting the mesmerizing sandwich dial and brilliant BGW9 Super-LumiNova execution that evokes a starry night sky. Some in the community, however, would have preferred a case size below 40mm, though the brand opted for 42mm for case shape reasons. Reviewers regret the choice of a see-through caseback over an engraved one that would better suit the thematic inspiration. Overall, owners and reviewers find the Gravithin ARGOMATIC - AM01 to be a beautifully executed watch, particularly for its dial and lume.
