Hello,
My grandfather passed away recently and he had this pocket watch. My grandma says it's an Omega, but we are not really sure. He got it from his parents in Soviet Russia, and he lived in Russia all of his life. We have no idea how or why his family got it. Please help. Thank you!
Firstly, I extend my sympathies on the passing of your Grandfather.
On to the watch
Nobody can tell you anything from those photos, othe than it's a pocket watch.
Here are example of photos that help us identify watches, in this case a pocket watch.
To help you take decent photos, place the watch on a neutral background and support your camera or phone, even using a tall mug gives much more stability than simply holding it.
Try to avoid direct lighting, subdued daylight near a window is good, using a flash is not good.
Firstly we need a clear shot of the front, showing markings on the dial.
Next, a shot of the inside of the caseback, showing any relevant markings.
And last but not least, a shot of the movement in correct orientation (crown up for a Lépine, crown sideways if it's a Savonnette/Hunter).
These were taken on my old iPhone 12 Mini and are unedited except for orientation.
Other useful information is the history of the watch (which you have provided) and measurements, most importantly the diameter in millimetres of the movement (the brass coloured part in the above example).
Let's know if you need further help.
