We've talked about a few different models in this thread, so I'll be model-specific with my feedback to help avoid confusion.
With my quartz (the Sead-sourced one), the issues I have seen so far:
- bracelet links of different widths (this was unique to me I believe)
- gasket easily bumped out of place when cleaning (otherwise, it sits where it should)
- clasp pushers sit at an angle
- bracelet is rough, and not well finished on the inside. It needs some attention to soften up. I gave mine a good clean, oil, and a significant dry buff to try to pull all the burrs off. Now, it's reasonable.
I'd still give it a "highly recommended" grade. Fantastic bang for the buck.
