Goldsmith Gallery is showing off its Remember Ring, which is a form of finger watch - actually, more like a calendar watch. It helps you with remembering (Remember-Ring, get it?) important dates, like say, your anniversary
Here's how it works: You tell the company the date you want to remember, and they set the watch. Then, as you wear it, a micro thermopile inside the Remember Ring keeps the battery charged and on time. Twenty-four hours before the date, a Hot Spot on the interior surface of the ring warms up to 120 degrees Fahrenheit for about ten seconds every hour, all day long.
