That's the only piece I disagree with. These are made in China. Labour is cheap. If they would have had any of these assembled, they would have popped out the innards of the watch (possibly scrapping the entire core, depending on how expensive it is to remove the taptic engine and solder on a new one) and put a new core in the body.
As the lines are designed to integrate the bands with the bodies at the end, they may have reboxed the bands as well (not retail boxes - the generic ones they use for internal, manufacturing stock - or trays, maybe they're on trays by the dozens). In any regard, they wouldn't scrap more components than they had to - that would just be silly.

You're still missing it. The duration of time from the raw steel starting to be cut to the band being boxed is likely over 9 hours, as they've stated the duration of time it takes to cut the links is almost 9 hours.
I don't think anyone is saying there's actually 9 man hours in a band.
(whether you have 9 people for one hour, or one person for 9 hours, that's the same amount of effort) THAT is man hours - I think that's what we're agreeing on.
What you seem to be disagreeing with is that the duration is around 9 hours. So, you're calling Jony a liar. Because I'm pretty sure it's him in that video that says that it takes nearly 9 hours to cut the links from a single piece of steel. (why they think it's important to say it's a single piece is beyond me...it's not like wood, where you're preserving the consistency of the grain or anything).
Anyway, I digress. It's duration. The actual time spent from the commencement of cutting to being put in a box that we're saying is 9 hours. Don't like it? E-mail Jony and tell him he's lying because you understand their manufacturing processes better than he does.
