Casio's Ring Watch, priced at $120, is back in stock on Casio's website after selling out in December following its launch.
The Ring Watch, also known as the CRW001-1, was released to celebrate the 50th anniversary of Casio's original digital watch.
The fully-functional watch features a sub-inch screen and includes spacers to fit smaller fingers. It can display six digits, has various functions like stopwatch and alarm, and offers standard or military time settings.
UPDATE: Casio has sold out of its online inventory of the Ring Watch as of July 1st. It was praised for its design and functionality.
