Changing clock to analog

I am creating a vivoactive 4s watch face and I want to change the digital watch to analog. Here is the code for the time so far: 

    private function setClockDisplay() {
    	var clockTime = Sys.getClockTime();
        var timeString = Lang.format("$1$:$2$", [clockTime.hour, clockTime.min.format("%02d")]);
	
        var view = View.findDrawableById("TimeDisplay");
	
        view.setText(timeString);
    }
    

Can anyone help?
