DOOM: The Dark Ages Pocket Watch Fan Concepts

I saw the DOOM: The Dark Ages trailer and wondered what kind of pocket watch would he carry as a token item if he were slaying hordes of demons.

It should have that sci-fi gothic feel, and also robust enough that it can withstand a beating. I started researching Rolex, Vacheron Constantin and large numeral "Goliath"-style pocket watches... and ended up also designing the dial and internal parts for the movement.

The watch hands would be powered by Hell Energy like the Crucible, and would also function as a flashlight/lantern for those nostalgic about DOOM 3 mechanics :D
