The 'Remember Ring' is designed to give forgetful partners a heads-up 24 hours before their anniversary by gently heating up on their finger.
The Lord of the Rings style band warms up for 10 seconds to 120º F, which is apparently hot enough so you feel it, but is not so hot that it burns.
The ring then cools down, but will continue to heat up every hour until your anniversary. Not irritating at all then.
Alaska Jewellery who make the ring explain on their website, 'Using a micro thermopile, The Remember Ring™ converts the heat from your hand into electricity, keeping the battery charged and microchip clock running perpetually. Just specify your anniversary date when you order, and we'll programme your ring for you.'
It's available for pre-order now for $760 (although if any future husband of ours suggests they need one, we're calling off the wedding. Just so you know.)
