There were no issues with excessive gap on the V1. A deliberate flaw to sell V3s I would say.
People like to say this... deliberate flaws. But what you have to realise is you're dealing with backroom/underground factories producing components. The way most of these outfits work is by several different factories producing different components. One producing bracelet links, another making cases etc. Then those parts are assembled together at another location it reduces risk.
But even though they reduce risk, it doesn't always work out. The authorities raid them, a certain factory gets shutdown. Or the skilled worker who use to make the bracelet retires/gets arrested/gets poached by another factory.
What I'm saying is, you're not dealing with Amazon here, you're not dealing with a reputable legitimate factory business that has the luxury of stability and regularity. Things change in this business and when things change, sometimes quality can reduce as a result. They make these watches in batches it's clear to see.
Anyway the 15202 flaw as you see it (your loss) is so minor it really is hardly worth mentioning.
