Vintage DIGITS Ring/Watch - Quartz
DIGITS is the BRAND....it is NOT a digital watch!
My Mom wore this quite often, when she was sewing and quilting. I'm pretty sure she got it in the 70s. It does show some wear, and a bit of finish loss, but it looks good. It was running until a sort while ago, so I know it does work. It just needs a new battery.
It has the expandable band. As it is, it's 3/4" inside diameter, and will expand out to about 1".
It also has one diamond (rhinestone, I'm sure) at the 12:00 position.
Cool....and functional, too.
