You are looking for something like this:

const pinch = Observable.fromEvent(this.pressGesture, 'pinch')
  .debounceTime(500);

The fromEvent method accepts types that conform to standard EventEmitter like interfaces and as such is able to automatically bind the event using the on method. This lifts the Gesture object into a stream and allows you to use the standard RxJS operators on it.
