I love those clocks! But from memory, the second hand gets "stuck" at 12 and then when it moves again, the minute hand advances at the same time. On this one, the minute hand jumps forward at the same time that the second hand goes to 12.

Some secondary clocks even used fully free-running second hands that weren't synchronized at all and so had no relation to the minute hand advancement.
