Each Wolf watch winder is meticulously designed and assembled by hand. The timepieces in your growing collection likely share that distinction and deserve the care a high-quality winder provides. The Wolf Cub is proportioned to encase your timepieces perfectly, with chrome finished hardware, black vegan leather, and a glass case cover. And while they rest inside the case, a patented turn-counting mechanism executes intermittent and bi-directional rotation programs through the silent motor that counts each turn, while other winders can only estimate turn counts. Available as a single or double winder, it can be run on the included universal AC power adapter for use in domestic and most international destinations, as well run on AA battery power when necessary or preferred.
