Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Islander Bayport Automatic Dive Watch for its versatile 40mm case size and retro styling, featuring a unique grey dial with a framed date window and a pie pan design. Reviewers and owners alike highlight the watch's well-executed finishing with chamfered edges, a tight 120-click bezel, and the reliable Seiko NH35 automatic movement. Accuracy reports vary, with some owners seeing between -3 and +6 seconds per day, while others note that the NH36 movement in comparable models can be regulated to achieve near-zero daily deviation. Overall, owners and reviewers consider the Islander Bayport Automatic Dive Watch an exceptional value proposition for the brand.
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.
