I have 7 watches that I rotate through, depending on the day and occasion. Two or three are my daily 'go-to' including a very neat wooden one, and a cool, steampunk-ish, brass 'skeleton' watch.
Yes, my smartphone does tell the time, but I've found that it can be cumbersome and awkward at times, not to mention requiring me to hold it in my hand to do so. I have found it's much easier, especially when I'm already holding stuff, to be able to just turn my wrist and look at a watch.
