If it's genuine, the counter with the Geneva stamp is really valuable. You didn't specify the model of the watch, and you didn't know whether it was a men's watch or a women's watch, and you didn't know whether it was a mechanical movement or a timely movement. 18K contains many meanings, such as 18K gold, 18K rose gold, 18K rose gold diamond, 18K platinum diamond and so on. I can only tell you that the price range is about 60,000-550,000 yuan. You'd better give a clear front photo so that everyone can appreciate your watch.
