Nope. I disagree. I would expect the indices to be centered with the seconds but they are not.
Sorry to be a little bit sceptical. Sala's book has its problems and mistakes, but the 12552 in it looks different:
Note how much wider the seconds and tachy scale are so that there is more space.
Additionally, I would expect the index at seven also touching the 12 hour counter on your watch but it doesn't.
