Identification Help with Grandfather's Watch

Many Omega models didn't have a particular name like Seamaster or DeVille. To have any hope of getting identifying information, it would help if you could start with some better photos. Here are some suggestions. Forget about the bracelet. Just take good in-focus photos of the watch itself in good bright natural lighting and crop them to size so they fill the screen. If a photo is out of focus, like the last one showing the dial, don't post it, just delete it and keep taking more photos until you get some good ones. Ultimately, you will probably need to have a watchmaker open the watch so you can take photos of the inside, since that's where the information is.
