Bezel is missing in photos. Impossible to replace. Would need a new case.
Polishing case destroys value.
Black dials are usually an indicator of a repainted dial. This one looks decent. Swiss made looks crowded at the 6. Others may know better.
Hands are acceptable. Sweep hand can be hard to source.
Do you plan to restore it yourself? If so best to practice on something like an A Schild movement (or a few dozen first.) Preferably ones that are working.
Restoration of this will be a money pit. Parts will average between 35 and 80 bucks in the US. There are at least half a dozen missing without even looking at the movement. Any problem with the balance or hairspring and another 250 or more. Rusted setworks, that is a couple hundred right there. Broken pivots on the escape wheel or pallet fork ...
If your really like the dial, then best to simply look for an Identical watch with all the parts that is running. Such a watch should be under 300. I personally would not pay more than 60 for the case and 30 for the dial. But I am cheap and started working with this stuff 30 years ago.
If you do not service yourself, expect to pay between 400 to 800 US fiat bananas for someone else's time.
I actually encourage others to take up watchmaking, It can be quite rewarding, fun and enjoyable. The more who do practice it, the more there will be demand for parts and instruction. And others to share technical details with. These are great watches to work on. Just not as a starter watch.
