I would buy a $20 watch from wally world. There are some in that price range witch have two timezones (useful for work) and decent bands (useful for comfort). The other 80 bucks I would use to pay bills, build my emergency fund, or put toward my retirement. If all those things were done, I would use the extra money to entertain a willing lady and have an agreeable meal.
(I choose to live below my means, and a watch is, for me, a tool, not a status symbol)
