Vintage Pop Swatches with major issues

Set of 4 vintage Pop Swatches , no bands available. These were tested yesterday at the Swatch store here in Quebec, 2 worked for a second or two and then gave up. I hope that someone will love these anyhow, perhaps make them into fridge magnets or such. (I believe that some were display only and wonder if they ever really worked. I did use 2 for a bit.) Great for a collection. From my drawer to yours☺️
