>It's not out of the ordinary to spend $400 on something like a Seiko or Citizen watch
That kind of depends on your definition of ordinary. Is it ordinary for somebody who buys a watch to spend $400 on it? absolutely. Is wearing a $400 watch ordinary? maybe not so much. Apple claimed to be selling more than Seiko or Citizen two years ago, and the apple watch was definitely a niche then. Apple has done well in the watch market but that's a long ways from iPhone-level success.
