Can you post a picture of the movement please. We would like to see the serial number that is stamped on the movement. Typically, you just need to open the back (some are hinged, others screw off) and then pop 1 more cover to get to it.

Assuming there are no extra screw marks that don't show up in the photos, the case and movement are likely an original combination, in which case the case will likely be from a similar era to the movement. The hands and dial also look "right" to me.
As you can see from the Total Production figure, this is a common watch. That said, the "Davis & McCullough Special" (private label) marking does make it pretty interesting. All in all, a nice, family piece.
I am curious as to what the problem is with the bezel?
Phew! Glass is pretty straightforward. A watchmaker will either have a replacement crystal or will have a source for one. If there isn’t one in your town write back for a recommendation. That is a really really neat private label model 1877 Waltham from the town of Waltham. Get it serviced before wearing it and it will last for generations to come. -Cort
According to this quote from the silver forum (925-1000.com), Davis & McCullough were located in Hamilton, Ontario. This would be more consistent with your Canadian case.
"Ammon Davis, Toronto, is opening up in Hamilton, Ont., where he has purchased the fixtures of the store formerly occupied by Davis & McCullough. He is laying in a new stock of jewelry."

The photos are all cropped pretty closely, but this is a hunter movement, and the dial photo in your first post appears to show a hunter bezel. Is it possible that the case is missing the entire front cover? Maybe you could post a picture of the complete watch from the front.
Either way, I agree with Cort... very neat private label movement!
