Model: Automatic Setting Analog Clock
Clock gearbox may be causing an issue with the optic motor. The gearbox is lubricated and may have accumulated dust particles.
Take the clock to a warm room, which allows the gearbox lubricant to warm up.
Remove its batteries and place it on its backside for the day.
The following day, grasp the clock firmly by its outside rim and tap the backside of the clock against a solid, protected surface a few times - do not tap it too hard to avoid damaging the clock.
Reset the clock by removing and re-inserting its batteries.
If this does not resolve the issue, the clock motor may be compromised.
