Flip "digital" clock
 

Hello people there,

I have I old Realistic (from late 60's) flip clock that are now slowing down. For these mechanisms, some lub typ helps, or simply is not worth due to natural "bearings" worn due to age?

I tried to lube this one year ago, and worked like a charm, but now is slowing down again...

Before lubricating anything it's always best to clean out as much of the old grease as possible first.

Thanks for the tip. Ah, this probably is the cause, then... I'm simply put some oil for testing, but, when it worked, I'm simply leave it, with the old oil dirt.
Since is easier to simply put without opening the motor and mechanism.

What kind of motor does your "flip dial" clock use? There were many different variations, of which the most common type of motor used by "flip dial" clocks were the old Japanese made Copal Motors which tended to have issues with seizing up over time and they could be "rebuilt" but it was kind of hard to do so without damaging the plastic housing cover that covered the motor gears.

Then there was the Intermatic motors like the ones used in the old Intermatic wall timers from the 1960s-1990s, those were actually a lot easier to service as you could just get parts by picking up an old wall timer from 1960s-1990s and strip parts from those, to replace the commonly stripped "idler" gear in them.

Finally then you have the Telechron rotor type and their knock-off counterparts which are always prone to seizing up due to old gummy oil that needs to be "boiled" out of the rotors and then new oil put in either through heat and a vacuum pump or by drilling a small hole into the back of the rotor and dropping a few drops of 20 wt motor oil into the rotor housing and sealing up the hole with a daub of solder and then either freeing up the rotor by using a pair of pliers on the rotor shaft or running the rotor with electricity applied to it through its stator coil assembly until it frees itself up.

Either way they're fairly simple to resurrect, when you know what kind of motor you're dealing with.

Thanks for the tips, I will open the clock again and check the motor type, and sent here some photos.

##BTW, the model is: Realistic Chronomatic 106.

For now, it are making some semi-intemittent mechanical noises. In some positions, the noise stops completely.
