Some people are bad at remembering dates. You don’t need to know the entire history of the world, but if you have a spouse, you’d best find a way to remember their birthday, and your anniversary. You can program your phone to remind you, but what if you could always wear a reminder on your finger?

The Remember Ring will guarantee that you won’t forget those specials days ever again. It is programmed to warm up to 120 degrees Fahrenheit for ten seconds every hour, starting the 24 hours before the big day. It runs on a micro thermopile which draws heat from your hand and turns it into electricity. It’s water proof and impact resistant, so the fact that you’re wearing a reminder ring won’t even cross your mind…until it heats up that is. This comes in seven different variants of 14K white and yellow gold, giving you a size range from 10-13. It appears this $760 product is only available for preorder at the moment, so who knows when you’ll be able to get one.
