Like unexplained watch habits, this hobby seems to drive us to do some crazy stuff. Like make unexplainable purchases.
Case in point. I have three copies of a very limited edition watch. Why? Because they have different rotors, that's why. And because it is perfectly logical to buy three of the same watch even though no one will ever see the rotor when it is on my wrist, or pretty much never for that matter. In my defense, one of the watches has all black numbers on the date wheel while the other two have roulette style date wheels, which means they actually look slightly different from the front every other day.
Sadly, that is not even the craziest reason why I have bought a watch. There are some I own which I couldn't even begin to explain the reasons behind them. I found a pocket watch in a drawer the other day that I don't even remember buying, let alone the reason why I bought it.
