Probably enough for watch companies to stoop to the low level of spamming my inbox every day for me to buy one.
I used to wear a watch in school and as a kid as I was kind of all over the place where there was not always a clock, especially when I was out with friends after school. Now I don't really have a need for one. I have a clock in my car, at work there's lot of clocks (none of them are actually at the same time though) and at home I have plenty of clocks too. And overall, I usually don't care about the time anyway, it's not like when I was a kid and had to be home for a certain time. If I'm out with people I don't really care what time it is.
