A sexagesimal system

Hours, minutes and seconds are an example of a sexagesimal or base 60 numeral system.

The number 60 is a superior highly composite number, meaning it has a lot of factors. This allows for some simplification when dividing.

Since there are 60 minutes in an hour, the hour can be divided evenly in eleven different ways (with sections of 30, 20, 15, 12, 10, 6, 5, 4, 3, 2 and of course 1 minute).

Coming up with and remembering 60 different symbols would be cumbersome, that is why we write the sexagesimal digit using the decimal system.
