Medetai 8+9 Automatic 9 Watch Winder  (Black, Off White)

"FeaturesThe internal parts of automatic watches are designed to follow the pull of gravity. Therefore, they don't have gears that must be wound with a spring. Instead, their tiny weights get pulled by gravity as you move and swing your arm, so little by little these weights are twisting around both clockwise and counter-clockwise, until your watch is wound up. Watches like this are called automatic or self-winding types, as opposed to quartz kinetic, or mechanical watches.SpecificationsModel: R4892EBFinish Type: Hand crafted with high gloss piano finish MDF sprayed paint, gloss finishing with plush velvet interior.
