I was given this omega constellation roughly 10 years ago by my grandmother. It was my grandfathers. It came with an aftermarket bracelet which was cheap and broken. It's a bumper automatic movement I'm guessing made somewhere in the early 50s but cannot find any watches online that have the same dial with the numbers only in the corners. Any ideas.?

 

It's a 18k or 14k reference 2652 with 352 or 354 movement. Google shows plenty of these. It's appears to be in great condition cosmetically. A nice strap can be had easily, but more important is to get the watch serviced properly by a competent watchmaker if you intend to wear it.
