Can anyone identify this watch/movement?

[Nodelicious]

Hello All,

Hi come with a request for some friendly assistance.

I have a vintage pocket watch signed as rolex on the dial and on the movement. I have not been able to identify the movement though. After much research I have only been able to locate one other Rolex pocketwatch with this particular movement on the internet. Most of the Rolex pocketwatches I examine in photographs have a different movement than the one in my timepiece.

I have attached a couple of photographs in hopes that somebody can assist me in identifying my timepiece/movement.

Thanks in advance for any assistance.

Any hallmarks? May help identify date and could go from there. To me, looks very unusual since ratchet wheel is not visible.
