Dexcom G7 wins CE Mark and features direct integration with Apple Watch

Kit for Dexcom G7 CGMS

Dexcom announced today that it has secured CE Mark (Conformité Européenne) for the Dexcom G7 Continuous Glucose Monitoring (CGM) system for people with diabetes in Europe, age two years and older.

Verily, a Google company, helped Dexcom develop this new and much anticipated Dexcom G7 glucose monitor. The G7 sensor units are 60% smaller than previous models and feature an all-in-one design.

One of the salient features of this new Dexcom glucose monitoring system is that it renders all the Dexcom readings and alerts directly to a user’s Apple Watch.

This feature arrives to users later this year in a future software release. And it should dramatically help Apple Watch users view their real-time glucose readings on their Apple Watch.

Dexcom is also working closely with its insulin pump partners to integrate Dexcom G7 into current and future automated insulin delivery systems as quickly as possible.

“Over the past 20 years, Dexcom has been one of the leaders and pioneers in advancing real-time CGM technology,” said Professor Partha S. Kar, OBE, national specialty advisor, Diabetes at NHS England and consultant endocrinologist at Portsmouth Hospitals NHS Trust.

“With enhanced features and added simplicity, Dexcom G7 hopefully makes diabetes management easier for both patients and their healthcare providers, something that is especially important as we see more and more evidence of the benefits of CGM in broader populations of those living with diabetes.”

The company expects to launch the product in Europe within the next several weeks. Dexcom also announced that an updated CGM algorithm would be made available this year with potential benefits for users.

  1. The blue Jay GTS watch connects directly to dexcom transmitter and has done since the G5 so all readings go to watch you dont need a phone .cant follow the watch though and it works by bluetooth its a great ..

  2. For the Dexcom G7 sensor, is direct connect to Apple Watch (without IPhone) available NOW ?

    Is direct connect with other watches available and/or planned ?
    For example, Garmin watches have an excellent connection to Dexcom G7 Sensors, but the watch only connects to a phone (which is connected to the G7 sensor)

    Please keep in mind, direct connection from a Smartwatch to the G7 sensor would be “magic” – imagine the sample scenarios:
    * play tennis (sensor looses connection to smartwatch – too far away)
    * swimming (you can wear the sensor and the smartwatch, but the handy is hard to take with you in the water)

    • Hi Gerhard,

      The G7 does not yet directly connect to the Apple Watch (Dexcom says that feature is coming soon)–you still need your iPhone nearby. The G7 Apple Watch app communicates with the iPhone app to get your current glucose value, trends, and a 1, 3, or 6-hour graph of your recent readings.

      If your iPhone is out of range, you won’t get updated glucose information on your watch.

      Currently, no smartwatch connects directly to the Dexcom, although this feature is planned for the Apple Watch. However, it’s a lengthy process since it involves a new set of clearances and validation studies.

  3. Those with Diabetes want a CGM watch independent of a phone or receiver.

    The technology is there but big tech companies put profit over people and so prevent releasing it!
