Wait til you start selling stuff around the house to buy watches, justifying it with "I really don't need a _________ (fill in object you're contemplating selling) anyway".
My wife always says "Shop Your Closet" before buying more clothes etc. My new mantra is "Shop Your Collection".
Nice buy. I have one on the leather strap. It is the original strap although it lost most of its bright blue colour. I found a replacement strap only in red. I thought it was for a different watch, but because it fits with 22mm at the ends I bought it. A year or so after buying the watch I came across this advert for the chronostop driver, on the internet. It seems this red strap was an original option for this watch. (See the chronostop on the right handside) It' a very comfortable watch to wear. I am going to attach the red strap when I get home in August.
