Why to large things seem to move slower

Just been thinking about somethjng. I imagined there was a giant ticking clock in the sky, so big that it covers the whole sky. Then, I would have a small watch in my hand.

Each second the clock ticks in the sky, should tick the same as my small clock, right? But surely it would seem to move slower? If not.. Then it would be moving insanely fast, right? And it would cover a large distance in that speed.

I can't imagine that the ticks would move at the same speed, in my small clock, and the giant clock... So mainly, would they both move at the same speed, but the larger clock would cover more distance in the same speed??

Just making my mind hurt trying to think about it. I don't study science or anything so just consider me a curious ameture

Any answers would put my mind to rest thanks!
