Everyone crowds Old Town Square on the hour to watch the famous clock do its thing. You'll push through masses, crane your neck, watch tiny wooden figures appear for literally 30 seconds. That's it.

Even during those magical sunrise hours when the square is otherwise empty, the clock show itself remains underwhelming. Clock itself is beautiful and worth seeing, but don't plan your day around the hourly circus. Go any other time when you can actually get close enough to read the astronomical details without being trampled.

The real interest is the clock's complexity when you can study it properly — Calendar dial, astronomical movements. Just not during the tourist stampede every hour on the hour.
