Casio F - 91W for me. I'm surprised nobody's mentioned it before. Time (12 or 24 hour), date, timer, alarm, day, little light to read it by at night and water resistant. Just come out of the washing machine and still working. A classic. Actually, I do get the beauty and engineering of those expensive watches but I would just lose it or break it or get it covered in something. And I'm also not particularly rich any more so need any money I have for guitars and fuel.
