Dial looks reasonably OK, might improve a little by cleaning but uf not its still OK. Hands will benefit from careful cleaning and reluming carefully. Movement will needfully servicing, the rotor can be a problem on these and parts availability isn’t great so hopefully its not too badly worn. A new glass is straightforward to fit, hopefully a new seal in the crown will get it waterproof againor possibly a replacement.
The case is a tricky one, my guess is that it was originally a brushed or grained finish. which could be restored, or it could be left as it is if you prefer.
The watch can be made to look nice and sharp, very wearable, with decent timekeeping and a degree of water resistance.
