Here’s the translation of a Spanish language forum post with the history of Cuervo y Sobrinos.

These silver cases are called “Niello” and were typical of pocket watches sold by Cuervo in the early 1900’s.
The case needs extensive work, which may not be able to be replicated now given the toxic nature of the niello process.
The movement should be able to be fixed and period correct hands fitted. The dial looks to be in good condition.
Good luck with the project.
