The 6 and 9 in the 12 hour registers should be very nearly closed, rather than quite open and there should also be half-hour markings. I'll stop finding things now, I promise!

You can live with it, as the vast majority of people wouldn't notice the difference - if you look for a replacement dial, make sure it has the same markers as this one as these are correct for the serial and the hands of the watch. Just had a rummage through my spare dials and I don't have a match but they do come up from time to time if you did want to go that route.
