The watchman (no joke)
Independent
sentinel
A person who loves football or a particular team is a fan; a person who enjoys watching a game is a spectator; a person who goes to watch the game in person is a patron (probably a fan also).
It stands for call back. That's the number you can reach the person who texted you at.
A person who makes documentaries is called a documentarian.
FPS stands for 'First Person Shooter' an example is Call of Duty 4 or Halo 3
That may be a maintenance man, a time-keeper, or clock (or watch) repairman.
a watch maker or to be precise a jeweller seeing as watches contain quartz i guess
I think I would describe such person as a tout.
The proper term is "omnivore." Unless you have to watch. Then I'd use "glutton."
A person that stands for equality is called an equal opportunist.
Only if the call stands.
