Identification Help: Omega Constellation

A lovely heirloom! The C-case Connies have a dedicated following here and lots of love. @DJG2645 has already pointed you in the right direction.

Looks like you have the correct brick style bracelet for it, which is a plus - these watches had the option of a bracelet at purchase rather than a strap. If the watch hasn’t been worn or wound for while, you’d best take it to an independent watchmaker for a service, especially if you are intending to wear the watch regularly. Once you find a good watchmaker in your local area (one who is used to working on vintage Omegas and is sympathetic to keeping things as they are), he/she can open up the case for you, photo the movement number and reference (printed on the inside of the caseback). If it is cal 564 inside, you’ve done well - one of Omega's most celebrated movements.

There’s an understated elegance about these watches - and they are excellent daily wearers, IMO.

👍 - if you post your location, members here may be able to make recommendations. The watchmaker will be able to confirm the calibre, photo the Movement number (which will help give an approximate date of production) and the reference. And don’t forget to post some lovely photos of the beast on your wrist when it’s all done!
