You are asking, “worth repairing, value”? For openers, the movement will require service, and possibly parts. You’ll need a new crown and crystal, and a strap or bracelet suited to the solid wire lugs. You’ll have to answer those questions yourself, after you find a good watchmaker who has experience with antiques. After he quotes a price, you’ll know if it is worth it. Before you go that far, in its present condition, it is only worth the scrap value of the 14-karat gold case. Maybe about 8 grams, at about $40 per gram, minus the gold buyers charges. And after you spend a bunch of money on it, it will still be worth about the same, or a bit more.
I have uploaded an image of a side view of the watch, with an arrow pointing to a sizeable gap between the bezel and the case back. Bezels on watches designed like your are known to stretch over time. When that happens, you might lose the movement, or damage it badly. You’ll need to determine how serious that gap is before you spend any money on it. Even after servicing, it is not really a collectible watch. So you’ll be left gauging the sentimental value versus the cost of repair. Worth it? Could be, to you.
