Tujibeay49KHz Ultrasonic Eyeglass Cleaner with Digital Timer, Suitable for Ultrasonic Cleaning of Machine Jewelry, Eyeglasses, Rings

I got this to clean a watch. I accepted that this would be a product that I would probably use only once but it is actually fun to work with and now my wife keeps giving me things to clean. Do NOT put the actual watch into the bath. Just the bracelet. Works really well.
