 Fully procedural and customizable nuke clock with a combination of different expressions to manage the hand vibrations after each second. I think this expressions could be useful to reproduce the pendulum physic of any analogic mechanisms.

Click Expression:

One clic each second, normalized to have 60 clicks to make 360 degree (1-(int(((frame+10)/fps))*6)-6)

Fricion Expresion:

A simple triangular curve to emulate the lost of power in time given by friction 1-((frame+10) % (fps/2)/(fps/2))*(2)+1

Vibration Expression (Low frequency), interpolated with friction expression above: ((sin(0.8*pi*(fps+10)/((friction.rotate.z*5))+1))*(friction.rotate.z*1))+(1-(int(((frame+10)/fps))*6)-6)

The final step “Alternator switch node”  is a simple square curve that cut the double frequency of the “friction expression”: for 25fps:         ((frame-15) % (fps)/(fps/2)) *(20/5) – (20/5) >= 0 ? 1 : 0

for 24fps :          floor(cos((frame+2.8)/3.8)+1)

A super thanks to Andrea geremia  for the clock graphic style!
