Let's also not forget that most humans have two wrists. Perhaps it will become fashionable to wear a smart watch on one wrist and a high end mechanical watch on the other.

Of course that would remove any remaining doubt that the purpose of a $60,000 watch is to signal wealth rather than tell time.

Alternatively, maybe we'll see mechanical watches with a smart watch "complication". At the very least I'm sure we'll see partnerships between (some) high end mechanical watchmakers and smartwatch platforms.
