✅

You can use deep in watcher to watch object properties change.

Something like

  watch: {
    form: {
      handler() {
        console.log('form change')
      },
      deep: true
    }
  },

As in document

To also detect nested value changes inside Objects, you need to pass
in deep: true in the options argument. Note that you don’t need to do
so to listen for Array mutations.

I created a demo here
