Amazon sells (direct listing) elegant slender simple "Casio" watches for $10 each. I bought a few.
After a few weeks one of them rattles.
So I lost out on that deal.
It might be counterfeit. Amazon is a shady place.
Or maybe it is just another race to the bottom. Maybe $10 is the only viable price, and that isn't enough to make a watch worth owning.
A "toaster problem" in other words.
