So how does the watch check sugar?
The watch for now at least talks to the phone that talks to the reciever that has Bluetooth. Out of pocket if you don't have insurance is about 1200/ 600 reciecer 600 transmitter. You then gave to buy sensors you gave to replace every two weeks. You have to install 2 watch apps to get the buzz notifications of a high or low blood sugar. Let me know if you have other questions!
You have to embed a sensor under the skin. That sensor is then attached to a Bluetooth lte receiver that will transmit data. Measurements are not done by the watch. The watch is just for you to use as a display to monitor glucose levels.
This is pretty cool and, clicking through the links, there's a video showing the insertion process. Ow?
That embedded sensor... how long does its battery last?
Sensor lasts 2 weeks. Transmitter battery about 6 months.
This photo (38mm watch worn on my right wrist) shows the Dexcom receiver. This is the unit that receives the signal from the transmitter unit attached to the subdermal sensor.
The transmitter is paired to an iPhone using Bluetooth LE. The Dexcom Share app, installed on the phone, has a component (pictured here and in the original post up top) that can also display the current reading on the watch. There is a lag of about one to three seconds before the current reading appears.

Some insurance may cover it. Call the member number on the back of your insurance card and talk with a rep, or ask your diabetes care provider. Dexcom CGMs are available for adults and pediatric applications.
I love having the ability to check my glucose levels at any time and have since I got a CGM in 2013. I got the Share version of the receiver when the original receiver failed recently.
