I have two old watches, my grandfather's watch and my father's watch. My grandfather's watch loses 5 minutes every hour and my father's watch gains 5 minutes every hour. Yesterday, I set them both to the correct time at 09:00 pm. When I woke up the next morning, my grandfather's watch showed 08:00. What time did my father's watch show at that moment?

(A) $09{:}00$ (B) $09{:}30$ (C) $10{:}00$ (D) $10{:}30$ (E) $11{:}00$
