This is a wind-up kitchen timer. * It's wind-up, so no batteries or charging are needed. * It can measure up to 60 minutes. * It ticks while timing, and rings briefly with a "jingle" sound when the time is up. Product Name: TFA Dostmann Analog Kitchen Timer Color: Silver Dimensions: Diameter 70mm x Height 43mm Weight: 104g Materials: Stainless steel top, rubber-coated plastic bottom. I used it for about a month and haven't used it in a while, so I'm putting it up for sale. Operation has been confirmed. Thank you.
