Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The JIANGHUN War Drum's dial is widely praised for its bold rose pattern and deep finish, with silver hands and indices complementing the design. Owners note the complexity and cost of manufacturing the case and dial, and one owner finds the bracelet overpowering. The watch features terrific lume, and its applied hour markers are noted as slightly misplaced with one numeral appearing misaligned. On balance, owners appreciate the JIANGHUN War Drum's unique dial and case design, despite minor alignment issues with the hour markers.
One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner noted that this manual wind Yema Diver, while featuring a cool patina, is unlikely to be waterproof or gain value, positioning it as a fun second watch rather than an investment. Overall, owners view the Yema Diver as a fun second watch rather than an investment, with one owner experiencing a water ingress issue.
The Swiss Sellita movement is a notable feature. Reviewers did not reach a consensus on any weaknesses.
