None – don’t often wear a watch as I’ve always got my phone with me and it shows the time.
See, this is what I don’t understand. Unless you’re one of those terminally tragic saddo’s who go everywhere with their bloody mobile clenched in their sweaty fist, to prove to everyone just how cool they are, it takes far, far longer to take a phone out of your pocket, wake it up, and look at the screen, whereas if I want the time, especially if I’m riding the bike, it takes one second to glance at the watch, two if I have to move my sleeve. What’s so difficult about that?
