I couldn't find a picture before, but just hunted one down of this watch:
which the wonderful bf got me for Christmas last year (in teal). It's got a negative/ positive display that changes at the twelves (ie the numbers are dark, the background light at midnight and vice versa). The thing I probably love most about this watch though is the way it tells time, which you can see on the photo. It brings back dear childhood memories of driving my mom crazy. I went through a phase (her "agita" phase) during which, when asked the time, I would say, "Oh? Um, 8 til." Or, "The time, you say? 39 after." At which point she would get comically red in the face and tell me not to do that, to just tell her the time in the correct way.
Ah, the good old days.
Also, this site has painfully cool watches.
