watch and commands/custom commands

On other devices/protocols commands and custom commands work as expected, but on watch I can't find the way to make it work.
Is me doing something wrong or maybe commands on watch are maybe diffrent or not implemented?

Have you checked logs to see if commands match documentation?

Hello again, finally didn't need it.
I was missing commands format but also didn't noticed there were already some commands for watch too.

Thank you very much.
