> Anyhow... those power sources should be irrelevant to the patent... they've existed for years by numerous players in the watch market.

This is my biggest complaint whenever there's a patent discussion on HN (or anywhere else) by laypersons. The power sources are highly relevant to the patent; Every single claim in the patent is important. Otherwise, someone back at the beginning of patent-time could have simply patented "thing which you wrap around your wrist" and owned the patent to watches, bracelets, and handcuffs. As well, there could exist pre-existing patents for a straight stick, a piece of string, and a hook; But putting them all together to make a fishing rod would be an innovation that you could patent.
