System app won’t perform this, and there is no settings to change that. Maybe check your wear apps and see if there’s any suspicious apps that is doing this in the background? I have an app called “Hourly Chime for Wear” that will vibrate my phone and watch every hour.
I use Hourly Chime on Android Wear. You can customize your vibration, so you know it is the hourly chime and not just a regular notification.
