Lifetimer

The Lifetimer takes the old adage "time is passing you by" quite literally by telling you exactly how much time has passed you by. Any significant event like a birthday, anniversary or your next holiday is marked and when you press the corresponding button, the Lifetimer tells you how much time until your next whatever, or else how much time has passed since your last whatever. Since life is made up of the little things as well, the Lifetimer marks your tea break, the time you leave work everyday, even the last time you were engaged *winkwinknudgenudge*.

Now, if someone asks you how long you've been with your significant other, impress them by stating matter-of-factly - "2 years, 17 hours, 47 minutes".
