After each revision and cleaning, the mechanical movement should be demagnetized either completely or in the disassembled state.
Especially the restless spiral can have magnetized over time, especially in older works. A harmonious oscillation of the spiral is then no longer possible: the clock runs inaccurately. Tools can also be a "source of danger" and transmit magnetism and should therefore be demagnetized before use in movements. With the push of a button and in milliseconds, Elma Antimag demagnetizes complete watches, disassembled movement parts, cases and tools.
Small parts should be placed in a sealed plastic bag on the field
Electronic quartz watches must not be demagnetized.
Mains voltage (Vac): 220-240 V
