The watch that countdown to your death

I was in the car on the way home listening to the radio as usual. Some interesting topic the DJ have on today, which is the Ticker watch. The watch that gives you constant reminder to when you are going to die. The funny part of the watch is that it actually aims to give you the actual time you have left before you die. Would you actually buy this watch?
 

Pros:

1.  You will be able to know how long more till your death and get everything needed to do before you died sorted.
2. Others won't be so shock with the news of you dying, and might be able to take the news calmly.
3. You tend to value the time and spend each and every second more wisely.
4. You tend to value life more and might even be more adventurous.

Cons:

1. The price of the watch might be too pricy.
2. You might spend the rest of your life worrying about your death.
3. It might not work as stated and you might be just using a normal watch and feel stupid afterwards for spending such a big amount of money for nothing. (P.s you might actually end up feeling happy due to not dying as predicted by the watch.)

Tell me what you guys think? For me if I were to wear that watch and know I will only be alive in a month time. I most likely quit my job and travel the world if I have the money or spend each and every moment with my love ones. Do things I will never do and  feed myself with all sorts of amazing food as I'm such a foodie.
