You can find the directions here: Install on Android Wear - xDrip+
If you need help, there’s a Facebook group called “Xdrip”, just like the app.
Yes, you need a phone to set the set the watch up, though I believe it can be done from an iPhone as well. I don’t have any experience with iPhone, but I know the required WearOS app is in the Apple Store.
Yes I looked into Wear OS solutions and it is still complicated, experimental and requires a Android phone running Xdrip for setup and iOS Xdrip seem even more experimental. For now the BlueJay watch is the best direct to watch solution and has good features, easy to use and pretty reasonable at $150 USD. It currently does not support the G7 yet, only the G6, but the developer says they should have a G7 update soon. My main complaint is there is no way for the user to update the firmware to fix problems or add features later.
@Mike_F Thanks for making this topic. It’ll be really helpful to people to have a broad list of options.
I’d been trying to figure out he Garmin watches that would work since there are too many Garmin watch models. At the moment Garmin has two apps so there are two lists of devices
Garmin Dexcom app (more features)
Garmin Dexcom Data Field (egv and trend arrows)
As previously mentioned Garmin requires the Dexcom app uploading your data every 5 minutes, the Garmin app downloading the data from Dexcom every 5 minutes then a bluetooth connection to the Garmin device to send the new data.
I found this mention in some xdrip docs about why it is so hard to make these apps reliable. xDrip Dexcom Intermittent Connectivity That doc is talking about the phone app, it is even harder on the watch.
When you started this topic in addition to a list of compatible devices you had some “why” questions. Are they any whys that haven’t been answered? And speaking of lists, please consider editing your first post, putting a table in with the lists and devices people have posted then asking a TuDiabetes admin to make it a wiki so you don’t have to maintain it.
I’m happy to report that I have everything installed and working the way I hoped was possible. The four pieces of hardware (t-Slim X2, Dexcom G6, Galaxy Watch 4 with Wear OS 4.0 and Pixel 2XL with Android 12 phone) are all set up with connections to two of the other pieces of hardware (which is the limit for each one). The t-Slim X2 is connected to the G6 as is the normal set up and it’s connected to the phone using J. Woglom’s ControlX2 mobile bolus program. (I installed the watch apps but they would contact and wait on the phone, so I deleted them.) The phone is connect to the t-Slim X2 and the watch in a normal watch-phone manner. XDrip+ is installed on the phone and the watch (Using Wear Installer 2.) XDrip on the watch is the only collector and is connected to the G6. It provides the bG complication for the watch face. XDrop+ on the phone is used to set up the watch and gets the info collected by the watch for it graphs, etc. XDrip+ and ControlX2 are both resident on the phone and work without interfering with each other. It’s great. I have all the info I want without taking my t-Slim X2 out of my pocket. The watch will report glucose levels without me having to carry my phone.
I have a similar setup. Please note anyone that wants to make this work without having their phone with them needs the Google Pixel Watch 2 with LTE connectivity. That watch comes in 2 models, wifi only will require you to have your phone with you, or the LTE model and you do not have to have the phone with you.

One additional final thought: Dexcom announced yesterday at their earnings call that direct-to-watch has now been submitted to the FDA for approval.
Direct to watch is finally approved. But only Apple watch will have it in the second quarter of this year?
“Dexcom announced that ‘direct to Apple Watch’ functionality for Apple Watch will have a phased launch available to all G7 iOS users everywhere by the end of the second quarter of this year. The announcement means that Dexcom G7 will soon be the only CGM system that can connect directly to Apple Watch without always needing to carry an iPhone.† People choosing Dexcom G7 to help manage their diabetes will have access to ‘direct to Apple Watch’ as soon as it launches in their country.”
This is good news. I wonder WHICH Apple Watches will be compatible though. As @Sue_R mentioned in Dexcom G7 and Apple Watch SE - #5 by Sue_R, her recently purchased watch does not support G7. I’m still using an Apple 4 so I hope it will support direct to G7, at least 'til I need to replace it with a newer version!
I dont know which models, as it did not really mention it. All I remember reading was end of second quarter this year. But I do not have any apple watch. I have iphone and macbook but not interested in the watch. I am using Garmin Marq, which has much longer battery. I usually charge it once a week only. My watch face (receives the dexcom CGM data(G6 or G7 does not matter, both are compatible) through the phone using the data or wifi, but of course I would love to have the readings in realtime using Bluetooth with the “Direct to watch” also. Maybe later in the future 
FDA 510(k) Decision Summary Dexcom G7 Direct to Watch
Once a sensor is paired to the iPhone that is paired with the Apple Watch the sensor will be able to send readings directly to the watch.
Dexcom bundles the watch app with the G7 iOS app. The current G7 app requires watchOS 9.1 or above. That’ll work on an Apple Watch 4 or newer, including the SE.
Off topic: The FDA released new cybersecurity guidance for medical devices in 2023, way after the G7 was submitted for review. Dexcom checked all the 2023 cybersecurity guidance requirements as part of the direct to watch submission. Yay!
I saw on another forum that Dexcom’s “direct to watch” feature is now live. The user reported they just got prompt in the G7 app to make it work.

Direct to Apple Watch.
I’m currently struggling to connect my pixel watch 2 with my dexcom g6. Glad to hear it works for you!
Can you give me any hints what you did to get it to work? Is there any special setting in xDrip which needs to get activated or something like that?
Would be awesome if you can help me here!
I will not have time to help you much today but can pick back up tomorrow. I have the pixel pro 7 phone and the pixel watch pro 2. The setup was easy and I used it first with Dexcom G6 and now with G7 as well. You can download the app from the Google play store to your phone. I then also downloaded the Blose watch app because the Dexcom app is pretty marginal compared to the Blose app. No x-drip or any other complication iteration. I am not sure if the Pixel watch 2 is compatible but Pixel watch pro 2 works great. I am contemplating to move up to the Pixel watch pro 3 soon. Let me know how you make out or where you are stumbling. It is an awesome app.
I believe that if the Decom G6/G7 app is not shown in the Google Play Store when you search for it on your watch, then your Pixel Watch model is not compatible with Dexcom.
You do need a separate dummy phone number for your watch. I remember it took me a while to figure that one out. Your watch should have given you a message to contact your carrier.
Thanks for the quick answer! That means it is working for you with the normal Dexcom G6/G7 app on the watch via LTE 
. I’m gonna try this out tomorrow and hope it works for me too 
The setup ist almost too easy… I wonder why nobody already made a small tutorial for this if it really works.
