Does the Redmi Watch 4 support incoming call reminder? And how to make calls?

Support. 
If you have an interest in receiving and making calls, please refer to the following information:
1. When the watch and the phone are connected, there is an incoming call on the phone. The watch will vibrate and ring to remind, and display the number or name of the caller (you need to turn on the address book permission first);
2. You can make calls through common contacts, emergency contacts, call records, missed call reminders, etc. (dialing is initiated synchronously with the phone). When the phone and watch are connected normally, you can use the watch to make calls on the phone.
Note:
1. The caller ID name is consistent with that on the cell phone; unfamiliar callers display the caller's number;
2. If Do Not Disturb mode is enabled, you will not receive incoming call alerts;
3. Bluetooth connection is required to receive call reminders.
