On the subject of the watch, tho...
I read somewhere that the muslims have an afterlife construct for bad people, where the bad guy relives the stupidest action of his/her life, or the day's events that eventually led up to his/her death, over and over for eternity.
(Reading the shitposts in this forum I sometimes wonder if in my former life I might have been the douche who raped Jims mom or smthg lol)
Mebbe Omar thought a second watch would give him some semblance of control over his own personal hell.
Maybe he was reaching for smthg like the Tom Cruise character in Edge of Tomorrow?
