There was a time when I would feel under-dressed if I didn't have my watch on, but to be honest, these days, I don't really miss it.
I'm so used to looking at my phone to tell the time (like, how did that ever happen?) or the computer screen in front of me that I haven't really used my watch since giving up full-time work nine months ago. Besides, even when it was working I took it off to type as otherwise it kept catching on the edge of my computer keyboard.
But, if I were to ever replace my watch I think I would want something like this amazing piece of kit.
P.S. I do not, and doubt I ever will, own a Rolex.
