My dad just found his dad’s Breitling and gave it to me. It’s a co pilot.

It appears they re issued this a few years ago. I've never been into Breitling but I really like this watch. I need to get it serviced and maybe the crystal replaced. It's either 1950's or 1960's it appears. Does anyone know about these watches? There is not much online because the newer one is what comes up.
