Help - Information about 19 century pocket watches

Hello,

I recently inherited some pocket watches. One of them have my great great grandfathers initials on its back and is probably from the late 1800s. The other one looks to be from the same time period. It would be greatly appreciated if someone would help me identifying the watches, where they were made and approximately what year they are form. I removed the dial from both to see if I could find any serial number.s

Here are pictures of my great great grandfathers watch (sorry if the pictures are to big):

Dial


Back


Echappement, ANCRE, 15 RUBIS


Fully working movement


Serial number: 35965


The other pocket watch:

Back


Engravings


Movement, not working (maybe broken mainspring)



271, same as on case


That's all the information I have. Hope that someone could help me, especially with my great great grandfathers pocket watch.
Thank you!
