Watch Guard 4 watch winder features a non-magnetic design that maintains sufficient kinetic energy for reliable operation of mechanical watches, helping extend their service life and keeping them ready to wear at any time. Flexible watch pillow and adjustable outer ring - The winder case includes a detachable watch pillow, so you can remove it when you need to store other jewelry such as brooches and bracelets. - The outer ring is detachable and installable, compatible with most watch sizes. Whether you have a small-size women's watch or a large-size men's watch, the winder accommodates them and provides care. Bidirectional rotation for stable winding - The device operates in a forward-then-reverse cycle: forward for 2 minutes, pause for 6 minutes, reverse for 2 minutes, pause for 6 minutes, then repeats. - Alternating clockwise and counterclockwise rotation delivers more stable winding power and helps reduce timekeeping errors. Large capacity for organization - The unit features 4 rotating display compartments and 6 storage compartments, allowing up to ten watches to be stored inside at once. - A single watch winder can address the storage needs of you and your family, keeping watches organized and ready to wear. Practical use scenarios - Daily readiness: keep your mechanical watches wound and ready to wear each day without manual winding. - Growing collection: store and organize multiple watches for easy access and protection. - Jewelry and travel: remove the pillow to store or transport other jewelry, or repurpose the space for traveling needs.
