A minority of owners express a preference for sapphire over the acrylic crystal and find its case proportions less refined than a competitor. Overall, owners rate the Lorier Neptune SIV highly for its vintage aesthetic and value proposition.
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.
