Watchmakers and watch manufacturers all over the world have been using the Elma watch winders for more than 50 years. The machines are used for developing watch works, for the final inspection after manufacturing and for the inspection of the winding mechanism for servicing purposes. The professional watch winders move the winding rotors of automatic watches, imitating the natural movement of the wrist that carries a watch. If the watches pass the test and they have a sufficient power reserve after winding, the watch work is classified as stable-running and cleared for sale.

From the professional unit to the specialized watch winder for collectors and lovers of precious watches the professional Elma units provided the technical foundation for the elma motion which was one of the units designed for use in private households. Automatic watches

were constantly kept running to prevent the gumming of the oils inside the watch works, to keep the watches ready for wearing at any time and to make readjustment of complicated watches unnecessary, e.g. of watches with eternal calendar.
