CASIO Limited Edition Gold Ring Watch

There are small watches, and then there's the CASIO Limited Edition Gold Ring Watch. Made from gold-finished stainless steel, it's made to be worn on a finger. Yet despite its diminutive size, it packs in quite a bit of functionality, including hour, minute, and second readouts, calendar data, dual time zones, and stopwatch capabilities, displayed on a 7-segment LCD with a flash function that emits light at certain times. With an inner diameter of 20mm, it's a size 10.5mm ring out of the box but comes with spacers to accommodate smaller fingers.
