WHY YOU ... !

How can you ask a question like this

I almost got a heart attack. The mere thought of it almost fainted me.
Joking aside. I have ponder on this question numerous time and each time I have no answer.
An easy answer would be my 1st serious watch. The one that my wife gave me. A truthful answer will be when I get down to 1 watch it won't stay "1" watch for very long. Watches tend to have baby, don't you know

Guys, not sure if this had been asked, if you had to make a choice and because it is a matter of utmost importance, that from your current collection of watches, you have to pick just one watch to keep for life, and forego the rest for a life and death situation, and no more future addition, just that one watch! Which would it be and why? Care to play. This is serious just like the hobby of horology. Which one?
