Do you find yourself needing to charge more often than you prefer? Are there features specific to AWU other than longer battery that you’re interested in?
I just needed to replace my S4, looked at all my options and got a (refurb) stainless steel 7 that has 90% battery health, because ultras are too big for my preference, and nothing offered in the S8 / S9 was worth the added expense. Now I still have the 4 as a backup for those rare times I need a watch while the S7 is charging, and we will see what watch SX brings next year if my 7 battery health is lagging in a year. And even then 99$ for a new battery is pretty affordable for such a pretty watch!
