Since I brought up the question, here is a clear answer from Apple's web site, and it is a good answer:
Battery service If your battery has a manufacturing issue that's covered by the Apple Limited Warranty, AppleCare+, or consumer law, we'll service your Apple Watch at no additional cost. Our warranty doesn't cover batteries that wear down from normal use. We offer out-of-warranty battery service for a fee. If your Apple Watch battery holds less than 80 percent of its original battery capacity and it's covered by AppleCare+, you will get Apple Watch battery service for no additional charge. We might need to test your product to find the cause of your battery issue.

Richard "He that cannot forgive others breaks the bridge over which he must pass himself," and we forget that only grace can break the cycle of ancient hatreds among peoples. (It is notable that while I have regretted not granting grace to others, I've never once regretted extending it.)" - Edward Herbert -- The following information is important for all members of the V iPhone list.
