Not that old compared to the proper vintage Speedy's on here (love that DON above!) but still one of my firm favourites
I've been wearing my 2013 Speedmaster Pro regularly since Thanksgiving, aside from 4-5 scattered days wearing my Rolex Pepsi GMT and a couple of other watches, and it's averaging about +1 to +1.5 sec/day on the wrist after being serviced in August.
