I'll be 60 years old by the end of the year. I lived in 6 European countries, vacationed on Ibiza, and had my share of the wild life between 1975 and the late '70s.
First, you don't want to deal with a gold digger. It's like a thief trying to steal from a thief. If you want to get laid and there is a shallow chick with fabulous boobs, looking for a guy who has money, I wouldn't call her a gold digger, as she's too dumb to pursue this with any degree of professionalism.
Now . . . let's say you pursue this shallow chick, and you want to get 'er done in one night, you'll have to have the entire package. You'll need to have the cover story, and it's usually that you are a successful somebody from another part of the country, just visiting this town. That saves you from the crib and the supercar (although you could rent one). But it also requires you to pay for an expensive hotel room. Then you'll have to have a roll of $100s in the pocket, which is easy, and spend several hundreds in the club on drinks. In the end, if her boobies are so nice that you are willing to spend $800 on getting laid, which is what a hooker would cost you, the watch is just a tiny part of the package. In such a case a solid YG President would probably be a safe bet.
In all other case, you'd need the crib, the supercar, spend $1,500 on the first night, $500 the next day, and she'd have to be a really special pray or you would have to be really stupid in order to fall for it. There are plenty of dumb chicks out there that you can get drunk for less than $100 and bang in her apartment afterward. With, or without any watch.
