Does the Dexcom ONE+ work with Apple Watch?
What Dexcom ONE+’s own apps (Dexcom ONE+ app, Dexcom Follow) do, from the maker’s documents.
Yes
The Dexcom ONE+ app has an Apple Watch app that shows readings, the trend graph and alerts. The watch gets its data from the phone, not from the sensor, so it needs the phone nearby. (App Store listing; Dexcom user guide, p. 24)
Dexcom ONE+ is not sold in the US. All facts here come from Dexcom's UK and Ireland pages, the UK App Store listing and the outside-US English user guide (mmol/L). Dexcom says Share and Follow may not be available in all regions.
With Glide
Yes
Glide has an Apple Watch app and two watch face complications. The watch signs in from the iPhone; the app shows the number, the change per 5 minutes, how old the reading is and the last 3 hours. (/dexcom#apple-watch)
