I was having a chat with coworkers this week about the circumstances that would allow you to get this watch:

This is a $35,000+ watch. That's an insane amount of money, but I'm not going to say that it's crazy - I once thought that spending more than $100 on a watch was insane - well, look at me now! (Roy leaves the door open to purchase ridiculous things in the far future...)

I think I've come up with a pretty useful rule to catching the upper bounds of how much you should spend on a watch: you shouldn't spend more than 1/10 of your automobile's (paid-off) value.

The pairing seems to work well. Just like cars generally have a range of $15,000 - $30,000 (for most of us mortals), a lot of the affordable watches fall within that price point. (To get a decent automatic, you're looking at least $1,000, with most of the watches falling towards the $2,500 price point - see Tag Carreras, Omega Seamasters/Speedmasters, entry-level Baume & Merciers).

For those of you with nice cars above that $35,000 or so mark, that gives you access to Panerais & IWCs:

(Entry-level on these brands'll cost you between $3,500 - $5,000)

And the gold standard that everybody knows about: Rolex. These come in above the $5,000 price point, which seems reasonable if you own a $50,000 car:

(I'm not a fan of Rolex - this is the only one I'd consider wearing - the Submariner No-Date)

Of course, this rule seems to break down at the upper bounds. If you were to get the A Lange & Sohne watch from above, you'd need to buy roughly two Audi R8s:

But maybe, the point of this person buying two R8s is to gift one to me! So yes, if you can afford that nice watch and you get two R8s, please give me one of the R8s (and please pay taxes).
