Yes but most eat a lot of battery in the process of cycles checking and displaying the battery status, I use pie controls that can instantly display the battery status and time, when I pull up the menus from any screen im in.
Do you mean pie controls installed on the gear let you see the battery level on the phone?
I can appreciate the concern of battery consumption with such an app/widget but if it could be set to poll only when the gear screen is on OR better yet, when the button/widget was pressed, that would be ideal. Wish I was smart enough to make such a thing.
I just double tap the screen with two fingers to quickly check battery level.

If you are using a custom launcher there are quite a few, you can use UCCW, Zooper or you could also find a battery widget on the playstore.
Otherwise tap your screen twice with two fingers and it will display your battery percentage if enabled in gear manager.
