Watch, clicking effect?

Hello Adobe Community,

I just made a clock/watch which each 3 hands move acording to the timeline, but the second hand moves quite smooth, but i was wondering what to do if i wanted it to move 1 sec at a time, so it makes a "ticking" effect, instead of the smooth effect. SO heres how i made it:

I made a clock without hands,

Then i added 3 handles (images) with anchor point in the middle, and then made the rotation on the second hand like a expression: "value+time*(360/60)"
Then i made the minute hand, and parented it with the rotation of the second hand, and divided by 60 for 60 seconds per. minute: "thisComp.layer("Second Handle NEW.png").transform.rotation/60"
Then i made the hour hand like the minute hand, and divided with 12: "thisComp.layer("Minute Handle.png").transform.rotation/12"

How do i make this to a ticking effect, instead of the smooth movement?

Thanks
