While we’ve seen USB-C used by Garmin on a handful of other devices this year (inReach Mini 2, inReach Messenger, Garmin Edge 1040, Edge Explore 2), all of those had USB-C on the part that plugs into the Garmin device. Whereas this time, Garmin has put USB-C on the part that plugs into the wall/outlet/etc… Atop that, it’s a new charging port design for the watch side, while concurrently offering way faster charging, taking just under an hour to fully charge the watch (compared to 2hr 30 mins for the existing Fenix 7/Epix series). It doesn’t sound like this charging port design is headed to other units though.

Last sentence is the most immediately important, but the fact that Garmin is trying new options at all of a hint of what's to come.
