Do you know what model is this?

Good morning,

recently my Grandpa died and he left me his watch.

Can someone please tell me what model is this (and a little bit of story about) or where I can find more info about?

Thank you very much for your time.

Regards,

Without more and better pictures it's not possible to tell.
I guess it's a calibre 83.
Get better close ups of the dial, crown, inside of the case back and the movement. Take note of the movement number and if there is any information inside the case back.
