Perhaps the dissing was a bit unnecessary. I own one and I like it a lot and think they are better then the bergeon variation.
To me this is just part of the many tools I have for my watches where some can be more practical than others - in this case it is more practical than most. Look at it this way, some of us baby or watches for a multitude of reasons and some just wear it like there's no tomorrow. Some watch owners/collectors like to have all kinds of watch accessories (like girls who like to have accessories?) and they don't serve much function, would that mean there is a feminine reason for it?
I like these stuff as they are watch related - like having 4 sets of Rolex SD tool/dive charts sets that i keep just for the heck of it although i dont have even half of the rolex watches to adjust the bracelets and add dive extensions to!
To the original question, yes, i do find use in it.
