So Apple updated their supplier responsibility website. I noticed on the supplier page Watch isn't listed anywhere. Perhaps that's because this list is 2014 only? But then I'd be curious to know where the 3,000 or so Watches Apple employees are using were assembled. Does Apple's design shop in Cupertino have the capacity to produce that many Watches? Or does Apple not disclose suppliers for products not officially on sale?

The Watch hasn't even been officially released and the website still has the disclaimer "This device has not been authorized as required by the rules of the Federal Communications Commission. This device is not, and may not be, offered for sale or lease, or sold or leased, until authorization is obtained." Why are you jumping the gun on suppliers related to the Watch?
