Here's a swell gift for the person you hate most in life. The Tikker watch is set to countdown to its wearer's death. Oh sure, its creators try to spin it as a timepiece of happiness. The box even reads, "Tikker: The Happiness Watch" (which will initially trick your nemesis, making the ultimate zing! even sweeter). They say its intent is to remind us how precious life is and how we should make the most of the time we have here. Whatever. I still say the Tikker is some morbid Edgar Allen Poe malarkey.
If someone gave one to me though I'd just set it for about 900 years. Positive thinking, dude. And I'm pretty sure Moses lived that long so there's even, like, precedent.
Those brave enough to wear a Tikker enter a few personal stats and let the watch's age and health algorithms set their magic Death Date. From there its top two rows start the countdown to bucket kicking in years, months, days, hours, minutes, and seconds. The bottom row tells plain old current time.
If you like the idea of a wearable Carpe diem! reminder, but aren't Addams Family enough to wear mathematically calculated Death on your wrist, check out The Accurate, a watch that more simplistically states, "Remember, you will die" on its hour and minute hands.
