First you have to declare your variable, like myProperty in this case, and then you have to make a @Watch('myProperty') to make the actual watcher for that specific variable.

@Component
export default class App extends Vue {
  myProperty: string

  @Watch('myProperty')
  onPropertyChanged(value: string, oldValue: string) {
    // Do stuff with the watcher here.
  }
}
