It’s an old feature that was for timing telephone charges. The charge ticked up every three minutes so you could time your call appropriately.
It’s an anachronism now of course.
I actually think it might have been the reason why they tightened the 10 on that dial. That one is the exception, they accidentally made it better than the others. 🙃
Found my first font gripe with it - the spacing of the 1 & 0 in the number 10 is different on the left and right subdials.
It’s also got the over-spaced 1s around the tachy scale. Ah well
