Apple Watch in Airplane Mode

The Watch needs to connect to the iPhone to make use of its features. As for workouts it will work fine and do all that you ask. It will monitor your heart rate. Times and stopwatches work.

The Watch connects by Bluetooth and only connects to the Wi-fi when not connected to the by Bluetooth

Hi guys, I would like to buy an Apple Watch 4 GPS and, for personal reasons, use it in "Airplane mode" for most of the day. I would like to know if, with the Apple Watch in airplane mode, these activities will work:

1) Training activity: training monitoring (calories burned, heartbeats, etc.) and route tracking

2) Cardiac activity monitoring, electrocardiogram and notifications related to heart rate and irregular heart rhythm

3) Setting of timers and stopwatches

4) Activities (with third-party apps) for sleep monitoring

It should do everything but maybe not quite as well as you would like. Regarding #4, I use a sleep app, AutoSleep, with my watch in Airplane Mode. It works fine but I can't access the data, most of which shows up on the phone, until I've deactivated AirPlane mode.

Yes maybe the Apple Watch is not for you. As the Watch doesn’t work independently of the iPhone in the way you want. I have the Nike 4 Watch and it needs a connection to either a Wi-fi or iPhone.
