Klarstein 8PT1S - Winder to Watch - Jewel to watch with mechanical rotation (quiet motor and transparent window) - Black (Watch)
The crown was received within the stated time, well packaged. However, the mechanism is not quiet enough to sleep beside. I add that rotation cycles are defined this way: position 1 clockwise for 1 hour and then 3 hours pose, position 2 anti-clockwis
