i collect watches (an expensive habbit) and i have to have all of them (13 at the moment) set to the exact same second, drives me up the wall if they are not, and since all but 1 are analogue time pices, its a huge pain in the ass, especially when the clocks change, luckily they all keep time very well, only the breitling loses a second a week.
