Nightscout on your Watch
Pebble Smartwatches
Pebble smartwatch use is a historic milestone of CGM in the Cloud. Pebble has been bought by Fitbit in 2016 and necessary resources have moved to archives and rebble.io. Pebble support is still maintained in Loop, AndroidAPS, FreeAPS and xDrip.
You can’t find the Pebble app for iOS in the Apple Store anymore. For Android you need to download it from APKMirror or APKPure.
For authentication and getting the watchfaces, the original server closed so you’ll need to register with Rebble.
You’ll find Nightscout watchfaces here. Search for Nightscout, CGM, …
Configure the watchface with your Nightscout site URL.

You can answer no to default watchface install so that you will be able to select another one. You can then decide to install or not the snooze control.
Android Wear OS smartwatches
With an Android smartphone.
Recommended: Install an old version of Android Wear on your phone (search APKMirror for example: Android Wear 2.9.0.185084575.gms) and pair your watch. Make sure to allow GPS and Wear OS access to position on the watch. Allow Wear OS to run in background on your phone.
Note:If you installed Wear OS, you will need to manually update the watch Google Play Services see here.
Once your smartwatch Google Play Service has been updated to a version above 9.x you can safely update Android Wear to Wear OS.
Change the watchface to match your app (in Wear OS or on your watch).
Install Wear OS on your phone and pair your watch. Make sure to allow GPS and Wear OS access to position on the watch. Allow Wear OS to run in background on your phone.

This innovative app receives data from various sources and visualizes it clearly on your Android smartphone, smartwatch (Wear OS, Miband, and Amazfit), and in your car (via GlucoDataAuto).
xDrip

Full xDrip wear documentation here.

NightWear
NightWear is a minimal Wear OS watch face and complication available in the Google Play Store directly from your watch.
It uses Wear’s standalone app support, so requires no companion app installed on the phone, or no phone at all as long as the watch has an internet connection. This also means it’s possible to display Nightscout data on a Google Wear OS watch paired with an Apple iPhone.
Amazfit Pace & Stratos (obsolete)
These watches are obsolete. If you still own one, an xDrip widget by Klaus3d3 is available on GitHub with its installation instructions.
Xiaomi Mi Band & Amazfit (WatchDrip+)
WatchDrip+ by Artem (bigdigital) is a companion app to xDrip: it pushes glucose, delta, trend and treatment data to Xiaomi and Amazfit watches as soon as a new reading arrives. It can also get its data from AndroidAPS. See Artem’s blog for setup instructions and the GitHub repository for downloads.

Direct connection: Xiaomi MiBand 2, 3, 4, 5 and 6; Amazfit GTR 47mm and 42mm, GTR2, GTR2e, GTS2, GTS2e, GTS2 Mini, Band 5, Bip, Bip Lite, Bip S, Bip S Lite, T-Rex Pro.

Fitbit
Fitbit smartwatches are being made obsolete
Google has discontinued the Fitbit smartwatch line: there will be no successors to the Versa 4 and Sense 2 (the Pixel Watch replaces them) and software updates are only guaranteed through 2026. In June 2024 Google removed third-party apps and watchfaces (including those below) from the Fitbit gallery in the European Economic Area: installing them from Europe requires a VPN connected to a non-EEA country.
