Cell phones has been with us for quite some time now. I remember people still wore watches during the 80s/90s. At least a watch won't die on you everyday. Surprisingly, I think watches can be use too when you're hiking, snowboarding, etc. You know, you just look on your wrist and behold... you can tell time. Did I mention that it looks great too?
I'd take my grandfather clock too if it is portable.
Anyway, I've been trying to save up for this one Movado watch. White frame, leather strap, automatic, and chrono. It can be casual, but also looks great for semi/formal. Stunning. Cost... $1600 last time I checked.
