Unknown Longines

Dear community,

I inherited this watch but have no idea of the model, dimensions, history. Would you please be able to help?

Also, if you might have any advice for its maintenance, it would be great.

Thank you in advance!

Looks like a ref. 7163-4 from the mid- to late 1950's.

Wow, thank you! May I ask how you knew this? Is there somewhere where I can read more about it? It seems to be still running well, without any maintenance.
