Hello. First of all, that’s good that you are asking before buying.
My first advice would be that you shouldn’t rush when buying your first watch. You need to do a lot of research to be in order to identify what’s a good deal and what’s not. Secondly, concerning the watch that you are presenting to us, the biggest issue here is the case, as you can see the gold plating is nearly gone from the case and there is many corrosion. Because of these issues the watch has a really low monetary value (I wouldn’t buy it at all).
I would suggest doing some more research, the pleasure when you get your watch will be greater, and most of all you will not have regrets. And in the meantime you can also look at the watches for sale here on the forum (at least you would be sure about what you have).
Cheers! 👍
