When daylight savings happens the clock automatically adjusts itself to the correct hour, minute, and second.
Atomic Clock Information:
Howstuffworks.com - How actual atomic clocks work.
This clock movement is NOT "Atomic." It receives shortwave radio waves, like an AM radio does, that tell the clock what time it is. I am in Pennsylvania, very far from the source in Colorado and this clock syncs up perfectly on a clear night. During the day the signal is weak and may not set the clock. Once you have the clock running it will "sync" itself up to 5 times a day and set the hour ahead and back during daylight savings time.
Step 1: Remove Dials and Clock Movement
Then removed the movement by unscrewing the nut on the clock face win needle nose pliers.
Step 2: Finish Removing and Begin Installing
Then prepare your new movement. The movement comes with free hour and minute hands so I picked out some different ones and bought a new matching mouse minute hand for an additional $0.35.
Step 3: Assemble and Let Your New Clock Set Itself
Set the clock:
Use the knob in the back to set the time 5 minutes before the actual time.
Put in the battery and wait for the second hand to come around to 12 again.
Hit the red button on the back at 12 and again when the hand comes around to 12.
At this time the second hand will double jump 2 positions at a time.
Press the button again to hear the signal strength for 20 seconds.
The clock should beep on and off, it it is a solid beep or no sound, then it has no signal.
Move it to a window facing Colorado and wait till night time when the signal is strongest.
