I see an "L T2" under the balance and from that will venture a guess that this is the movement according to Dr. Ranfft

Looks to be a silver, silveroid, gunmetal case and overall it's had some dirt an moisture intrusion. The balance is not
shock protected. If you hold the perimeter in your fingers and gently turn it back & forth does the balance wheel turn
or the seconds advance slightly? If not then only a watchmaker will be able to tell you if it can be restored to working form.
You won't be able to do anything with the dial. The dial looks to me like late 1920's or early 1930's. Where are you located?
