The Landeron actually says Hahn Landeron on the movement. The research I found on the watch was that it is made by a company call Hahn in the town of Landeron. Later on the company just went by the name Landeron. The Landeron is probably from around 1890s.
Here is the Longines:
The serial number is in the 132k range which dates it to somewhere around 1875. Not sure if the case is original. The movement is strange.. you can wind it and set it from the back with a key, or stem wind it and set the time by moving the lever. Too bad the dial is messed up. Cool hands though!
The case was gold plated. The gold is still on the inside, but all but worn off on the outside.
