I use a watch. Mostly an aesthetic choice, as I do carry a phone, but I prefer using a watch to keep time. I'm old fashioned like that. I have two wrist watches. My "beater," a cheap ($20-$40 retail) Timex that I use for general wear, and a more expensive (But still inexpensive, ($80-$120)) old Seiko dress watch my dad gave me for my 18th birthday, for more formal occasions. Neither are vintage, but the Seiko was made around 1999, not quite vintage, but getting there. I think I have a "newer" pocket watch floating around somewhere, I remember picking one up at an estate sale. I think that pocket watch is vintage, but not by much, probably an 80's number. I almost forgot, one of my family heirlooms is a vintage Elgin pocket watch that once belonged to my grandfather. That watch was probably made sometime in the 30's or 40's, probably worth a good chunk of change. Honestly, I love to buy more vintage watches, but I'm one of those assholes who would love to buy more vintage everything.
