Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Aquastar Benthos Heritage for its fantastic looks, vintage charm, and excellent lume on the dial and ceramic bezel. Reviewers note its robust build and comfortable wearability, with one owner highlighting the brilliant cushion case and sunburst finish. The 42mm case wears comfortably despite its heft, and the watch offers excellent legibility. However, some owners find its 16mm thickness excessive and a potential wearability issue, while others consider the 500m WR designation superfluous given its 200m rating. On balance, owners and reviewers rate the Aquastar Benthos Heritage highly for its vintage aesthetics and strong lume at a good price.
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.
