Identifying my Vintage Omega

Try to take some better photos in natural light instead of shadow. You can crop out everything else and just post high resolution photos of the watch itself. Take photos from a few angles, including the back. Most importantly, have the watch opened and post photos of the movement and inside of the case-back, clearly showing any numbers. We will at least be able to tell you the caliber of the movement and approximately when the watch was made. It won't have a model name, but possibly a reference number, although it may be a nationally cased watch.
