In fairness to the seller, he sent videos of each watch working and pictures to show their condition prior to shipping.
In fairness to you, the seller appears to have no idea how to properly pack a watch and should be held accountable for the damage caused by ignorance.
Were the watches simple bubble-wrapped and then placed in a plastic envelope?
There are a number of good ways to pack a watch prior to shipping . . . and wrapping it in bubble wrap and sticking it into an envelope is not one of them.
Perhaps I misinterpreted the photos?
At the very least, each watch (and not a handful of assorted watches) should go into a hard container of some sort. There are specialized boxes for this such as a "Rolex shipping box" one can buy on Ebay, but a Tupperware or other plastic box will do, with a bit of bubble wrap to keep the watch stable inside the packaging.
Then . . .
The hard box should go inside a well-made cardboard box of some sort with packing material suspending the hard plastic box packing in the center of the cardboard box.
My watchmaker uses a cellular foam packaging material with a hollow center that fits into a proper box which in turn is placed inside a Federal Express shipping box along with foam or "styrofoam peanuts" to prevent internal movement.
There always needs to be at least some reasonable "crush-proof" aspect to the packaging.
