I never use my cell phone for time reading, dunno i find it against nature, after all it's just a digital watch on a phone, who says it's accurate (just the way my brain takes it), and who says the battery life doesnt affect it (when you take battery out you have to reset, and stuff).
I think those nooka watches are quite interesting, but har to tell time, one of the nice things about analog is that you can esily picture the day in the circle, i mean, at a glance, the small hand pointing down says it's time to go home (if you are really lucky), rather than just saying it's six.
Agree with cha, watch is a matter of fashion, it's telling to the world what you want to be seen as. Males have few things to
define their style in terms of accesories, mainly shoes, watch, glasses and maybe some devices, but they still do not compare with a watch in terms of fashion statement.
