This is the VERSOS winding machine, automatic watch winder, silent VS-WW011, white. I purchased it in 2017, but haven't used it much and have kept it stored away. A winding machine is essential for automatic watches to keep your precious timepieces running for a long time. It is globally recognized and uses a Mabuchi motor known for its quiet operation. It can be used without concern in bedrooms or studies, not just in the living room. It supports major watch brands such as Rolex, Omega, Tag Heuer, Breitling, Cartier, and SEIKO. It's compact and designed to match any interior as a watch storage case. Recommended as a first watch winder. Power supply: AC100-240V 50/60Hz DC4V 500mA Power consumption: 0.12W Set contents: Main unit, power adapter, attachments
