A:Answer The Samsung Galaxy Watch5 does not yet have the ability to measure Glucose directly as a Dexcom or Freestyle CGM can. Currently, "Raman Spectroscopy" is not currently a feature on any watch. Apple, for instance, says that feature is not coming for another "three to seven years" according to most news outlets.
From what I understand, however, Dexcom users can install a widget onto their watch that will display their Glucose readings on the watch, but still ultimately requires an Android-compatible phone. For example, if you have your watch on and you go out, but leave your smart device at home, you will not receive any CGM updates.
