Just got my latest batch of watches from the DHGate vendor at the top of the thread. I have gotten MoonSwatches from several vendors- I think this one might be the closest to gen- but I like the case color of some others..
the far left was one of the ones that objectively is a better quality watch because it is actually a steel watch case they simply coated in plastic and has a crystal- but is the furthest from gen.
the next couple are a jumble of Aliexpress and God knows from where purchased M2M. The second from left case looks super cheap and the color is way off from gen- but the dial is pretty nice. the empty case and the one I modified with red hands have a better colored case- but the dial isn't quite as nice as far left or second from left.
The far right is today's acquisition from the DHGate seller of discussion. Though objectively I do not care for the case color as much- seems a bit too light blue- comparing it to photos from the Swatch website seems the color closest to gen. it does not however have the metal weight inside to add heft as some do- but it does appear to have a genuine Renata battery.
I have another Neptune arriving in a couple weeks to do a build for a friend from the same DH Gate vendor - will be curious to see any color differences.
