there were real world hints though. It came from dividing a day. 12 hours first half plus 12 hours second half. 12 because every single civilized society figured out 12 has the most divisors proportionally to how large it is in the nearest vicinity. Then we divide to prima minuta (first order smaller part) to 60 parts. 60 has even better relative ratio of divisors. Then secunda minuta, the second order smaller part. 60th of the 60th of the hour.

It's not enough of the precision for the modern time so we redefined it, but we aimed for the redefined second to be at least just as good as the OG one.
