I would like to share my vintage Heuer Autavia 1563 cal. 15 with a nice aged silver dial that is turning to light gold color. The 1563 is an alternative model to the 1163 with identical cases and bezel. The 1163 uses the cal. 12 movement. The 1563 has a simplified dial featuring a running second hand at "10" o'clock and a 30 minute counter at "3" o'clock. This quite a large watch at 43mm.
