I want my phone to dictate the hour, and other specific things

Does anyone know of a phone app, or maybe a feature I can enable, to have my android phone dictate the time on the hour? Not loudly, and yeah I could look at my phone. I just never think to honestly.

Equally, I’m looking at getting a smart watch soon to replace a fitbit. Is there a smartwatch with this feature? Or maybe buzz on the hour?
