Project 1: Small magnets / micro magnets in Stepper motor in the watch
The stepper motor in the watch comprises the stator made from soft iron and which houses the rotor or armature, which is a permanent small magnets / micro magnet. Each pulse from the coil magnetizes the stator, creating a magnetic field which opposes that of the permanent magnet / micro magnet / small magnets in the rotor, causing it to rotate by 180 degrees. The next pulse, whose polarity is now reversed, completes the process by inducing a further 180 degree turn of the rotor. Each pulse from the coil magnetizes the stator, creating a magnetic field which opposes that of the permanent magnet in the rotor, causing it to rotate by 180 degrees. The next pulse, whose polarity is now reversed, completes the process by inducing a further 180 degree turn of the rotor.
Project 2: Tiny magnets / small magnet / micro magnet in the MegaQuartz
Upon pushing the stem back into neutral position three tiny magnets in a double-layer intermediate setting wheel are attracted by a steel setting gear and automatically correct the final position of the hour hand so that it corresponds perfectly with the minute.
The coil in the motor module is securely hidden in between two small strong magnets / micro magnet so proceed by removing (sliding) the small magnets from the motor and check resistance of the coil. Dip the motor in alcohol for a longer while and with a small gentle brush remove any battery residue or dirt that might be jamming the escapement.
Tiny Magnets / micro magnet in LONGINES ULTRA-QUARTZ
The 4.3kOhm motor coil was probably a quick-fix and was simply glued to the torsion bar. This solution did not prove reliable thus finding a working watch is a real miracle. The coil is totally exposed and vibrates in between two micro magnets / small magnet - the least amount of shock during wear will cause the coil to move and scratch its surface in the small magnetic gap.
