I found out that Google TTS can even tell the time in regional language, not just numbers but with morning, afternoon and evening information which is very cool.
No need to see a watchface, The voice can be sent to your ears via Bluetooth.
Adjust the frequency based on your preference.
Select your local language (french, Spanish, Hindi etc many more supported) in say task, prefer unchecked 'reduce resource usage' in Tasker preferences if you are facing issues with Google TTS engine not working.
Works in offline mode also, it needs internet connection first time only at the time of downloading the language specific data.
This can even be triggered by a AutoVoice action 'what's the time' !!
