Please note the crystal does have a small nick on the right side you can still see everything just fine on the gorgeous watch face the watch would look so much better with a new crystal. Yes it has been running without stopping for over 3 hours now without stopping I'm sure it could use a good cleaning as all vintage watches need to be cleaned every once in a while to keep it running its best the date needs need to be adjusted. It overall looks great for its age. It has scratches and a a small nick on the right side but you can still see everything just fine on the gorgeous face it would look so much better with a new crystal. 41mm without counting the crown.
