WATCH WINDERS Elma motion Style IV PIANO SILK for 4 automatic watches

Mechanic watches should not only be "fully wound up", but be operated using the full power of their main springs
sleeping phase: several hours (start can be programmed individually) of idle time per day allow the main spring to unbend, prevent unnecessary strain on the winding mechanism and so serve to keep the accuracy of the watch
Depending on the watch work, a mechanical watch has a special winding spring and therefore needs to be wound at an individual winding speed.
adjustable number of revolutions: 650-1800 revolutions per day guarantee the optimum winding rhythm and prevent overwinding and malfunctions
The direction of winding is preset by the manufacturer
individually adjustable winding directions: left-hand winding, right-hand winding, left-hand and right-hand winding alternatingly; all three winding modes prevent unnecessary idle phases and prolong the service life of the battery
Speed winding of a stopped watch
speed winding: ensures that a sufficient power reserve will be built up in a short period of time
Battery indication for safe operation of the elmamotion watch winder
low battery indicator warns if remaining energy will hold for only 3 - 4 more days; guarantees change of battery in time to prevent the troublesome resetting, particularly on watches with additional complications; battery running time at least 1 year
