The Remember Ring is designed to do exactly what its name says it will: aid in remembering an important date or event. Each ring has a tiny clock and battery within and, to remind you of a special day, it gently heats the ring up to 120F for 10 seconds on the hour, every hour for that entire 24-hour period. The rings are waterproof and come in yellow and white gold. The website has some conflicting information about the ring's availability, so it is best to call for more information. Assuming, of course, that you remember.
