Can someone tell me anything about this watch?

First of all. I am sorry I don't know anything about watches and collecting them. I inherited this old omegawatch and it's going to be a gift very soon. It's by my guess from somewhere between 40s and 60s. It's mechanical and manual and gold. I can't find any inscription or serial number. ( I know for sure it's an authentic omega) I would like to know if it is a nice gift.
I am really thankful if anybody has the time to answering me.
The photo shows the original strap next to the watch ( or what you call it in English)

As @ahsposo said, everything you need is on the inside. Also, include photos of the back of the strap and the front and back of the buckle.

Yes for sure I created two threads Yes I am wiser now. I should have read this first of course. It's not possible to open the caseback myself?
Thank you very much for taking the time.

If you really know nothing about watches or collecting, no. You may damage the watch.

It looks like s nice 30 caliber watch. But as said above, more info with pics of the movement and the case back.

Ok thanks a lot! I will bring it to a watchmaker and retur! 😀
