This item was specially given to me by an authorized dealer upon the purchase of a Rolex. It is a very rare item and is no longer available. This is a high-end novelty winding machine produced by Rolex for its premium customers. The luxurious feel, including the weight, is incomparable to other winding machines, and is typical of Rolex. The main body of the case is leather-covered, with the word "ROLEX" embossed throughout. Rolex high-end novelty item (not for sale) Size: 100 x 100 mm Battery operated For one watch As it is quite old, there is stickiness due to aging on the black part inside. No stickiness was observed on the embossed areas on the sides. I don't think it was ever used, but those seeking a perfect item may want to refrain from purchasing. It moved when I turned on the switch.
