WOLF1834 Axis double watch winder with storage. Powder-coated or copper-plated, laser-cut, perforated steel combined with clean, sleek lines. The Axis collection offers a modern, bold look for storing your timepieces. Our patented technology, which counts the revolutions of your watch's axis, guarantees precise revolutions per day. Size: 33.9 cm L x 20.8 cm W x 22.5 cm H Patented innovation: Every WOLF winder counts the exact number of turns. All other winders estimate the number of turns Dynamic cuff with locking function: The patented dynamic cuff "locks" your timer into the rotating drum, ensuring a secure fit. The low-density foam adapts to all wrist sizes without putting pressure on your wristband. Rotation options: 10 second start delay. Can be set between 300 and 1,200 TPD (rotations per day). Double the number of TPD by selecting the bidirectional setting Settings for the direction of rotation: Clockwise, counterclockwise and bi-directional Power reserve setting: 6 to 72 hours in 6-hour increments for watches with a power reserve so that the watch has time to release the stored energy before the winding program begins Battery: Can be operated with AC power (universal adapter included) or D-Cell/lithium batteries (not included) Storage: 2 winding modules, 1 piece of watch storage and travel case Material: Vegan leather
