This is a Sentinel Pocket Watch. I think that I've narrowed the era down to the 1930's. I feel that the face is consistent with that time period, as well as it being a wind up. It is in very good condition, still functioning. It is, however, very plain and much less ornate or decorative than other vintage pocket watches.
With the help of some friendly commenters below, I was able to pop open the back of the watch with a small flathead precision screwdriver and narrow down the date. Way off from my initial guesstimate. It appears this watch was produced in the late 50's-1957!
