Granted, the new feature seems to only be present in the beta version of Google Maps, it’s a clear sign that all Wear OS smartwatches will eventually get support for offline Google Maps.
If you’re already enrolled in the public Google Maps beta program, you’ll be able to use Google Maps in offline mode if you install version 11.140.0701.W (or higher).

The report also mentions that besides syncing the offline maps already installed on the phone, the watch app automatically downloads a map for your area. It’s also important to mention that maps are automatically synced when on Wi-Fi and charging, except for the initial download.
Once again, this isn’t yet available for everyone, so unless you’re enrolled in the Google Maps beta program, you won’t be able to use offline maps yet.
