How do we know they're using retail models?
store displays always do.
Don't really understand why this is such a big reveal. They have to have some way to trouble shoot the watches. doing it by wifi or bluetooth won't work if one of those is the issue so they need a way to plug in. and they don't particularly want store staff to have to open the whole thing up to get a connection

The ones in store sync with the iPad screens based on what screen you are on on the watch for education purposes.
That's only for the hands on demos. the ones in the case and the ones for try on could be totally the same as the retail units

In case no one has figured it out yet, the watches in the stores that everyone is playing with are not necessarily production models. Remember that you cannot buy one yet and it could very well be that these are late-production prototypes.
Just sayin'
Even my boyfriend's mid sized store has like 50 watches between the case, 4 sets of try ons and 3 try on cases. times that by like 260 stores just in the US. You really think they had that many prototypes
