well i for one don't use a watch, but I have a nice pocket watch, i had to bring in to have battery replaced, i could not for the life of me get it opened,

this may sound weird but you can ask deb about it i can usually guess the time to with in ten minutes I have no idea i have always been able to do this i have a good internal clock i guess, really freaks out my kids and deb lol, I did it at the hospital(this weekend) twice to same doc, and the doc looked around for a clock but it was on wall behind me, she even asked how did i do that

[personally i wouldn't spend a lot on a watch i break them or lose them ]
