I wear a watch because it looks good and is the only form of jewellery I wear. Never used to wear one, but never really take mine off now except to sleep. There's times that I need an accurate timepiece where I'm not near a phone or other timepiece (for example, aircraft or areas' that don't allow phones). I also means that I don't have to rely on my phone's ridiculously short battery and can get a quick time update at a glance. Plus I can use mine to navigate and as it's an automatic, never have to worry about the battery. I'm currently overseas, and bought myself a Casio F-91W to keep as my "other timezone" watch. Yeah that's right, I'm wearing TWO watches. Scott.
