Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The red bezel is a standout feature. The watch wears small, which is a concern for larger wrists.
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 notes this manual wind Yema Diver has a cool patina but is unlikely to be waterproof or gain value. Overall, owners view the Yema Diver as a fun second watch rather than an investment.
The Swiss Sellita movement is a notable feature. Reviewers did not reach a consensus on any weaknesses.
