A little correction from someone who happens to wear one: An actual Timex will probably run you $30-50, depending on how good a deal you find. Walmart knockoffs are cheaper, but much less durable; I bought one once, and the face was almost unreadably scratched within a month.
It's not a piece of jewelry, i.e. a status symbol, but it's comfortable, inconspicuous, and functional. It gives me the date and time at a glance, is accurate, times things, and has an alarm. I can strap it on my wrist and forget about it, because it lasts years on a single battery, and endures in the face of dust, water, scrapes, and bumps.
I actually think Pebble is going in the right direction here, with longer battery life and color e-ink, but smart watches have a long ways to go before they can compete with plain old digital watches. I have to worry about charging and protecting my phone, as I would with a smart watch, but my current dumb-watch is entirely worry-free.
