Winding machine, holds 2 watches, storage for 5 watches I've forgotten how many years ago it was, but it's quite old. In photo 7, there's a part that goes inside the watch that's peeling off a bit. However, it's not visible when the watches are displayed. It comes with an AC adapter and batteries, so you can use either. ↓Items included↓ Main unit, parts to hold 5 watches round, Dedicated key, AC adapter, instruction manual (single sheet)
