Probably the best and most functional watch I've ever owned was a "Casio - Moon Phase" back-lit LED, I think that was the name. Cost was $12.95. Never had to replace the battery. I would use the stopwatch function to race myself to work every day, got to be a real "thing". I realized it was really getting reckless and so I took the watch off my wrist while riding and tossed it in the woods. Pleasant trips after that. Haven't worn a watch since...that was 1982!
