·That dial appears to be 100% original.
I've noted your arrows and concern, but don't really understand what you're suggesting it ought to look like.
I found the arrows not in the right middle of the numbers. For instance on the 1st picture, 40 minutes, the arrow looks in front of the "4" and not right between the "4" and the "0". Same for "35min".
May also be an optical illusion due to the photographer's orientation.
