Here's an example of how packages are treated in the Chinese postal system. It's not suprising a few arrive damaged.

If I ever receive a DOA, I am defiantly sending it to a smith here in the US.
I would rather haggle with the TD for a discount on my next order than leave it to China Post or lost in China transit.
I thought UPS was a disaster, but after watching that video and reading the 3 to 4 month wait time, I prefer to have a good service done on a watch I really wanted. After the service, it should be fine for years.
