Are you serious? Yes, people wear watches. Here's something that will astound you: some people wear nice watches. The steel Submariner 16610 in the picture is around $7,500 new.
^ Correction, the Sub in the pic is NOT a steel version. The blue dial and bezel subs are ALWAYS white gold, hence the price is around 22k to 24k (check Rolex.com). OP if you were considering getting the Sub, get the used steel version with a V-serial or higher for around 5k. You can also opt for the non-date sub which I've seen go for $3800 (you can check for listings on Rolexforums.com). I would stay away from Sub ceramics, aka the new subs, because they'll run you over 8k easy.
Another correction, while the Rolex may be mainstream these days... that to me just proves how good they are. No wonder Rolex took precedent over Omega years back as the new benchmark. Also, Rolex's do hold their value, MUCH better than other brands - the demand for them are so high, and with each serial having a limited run, you can get back around ~80% of what you paid couple of years down the line.
Yet another correction, Rolex, as a brand, does make many other styles of watches that have nothing to do with diving, ie Daydate, Datejust, Explorer, GMT-II, etc. It just so happens that in the 60's Sean Connery wore the Sub in the Bond movies and so Rolex became famous for a diving watch/original 007 watch.
Enough with the corrections. OP, I would advise you NOT to get a Rolex off loans. The economy partly went to complete **** because of your type of mentality; and while you probably won't default on your loans, it's still a bad deal for you down the line because you'll end up paying more than what you should for the watch.
Plus, if you have to buy the sub on loans, boy you better have money saved up for repairs. God forbid something goes wrong (such as replacing a cracked crystal face) - good luck.
