People are diverse and their preferences are correspondingly diverse. Some might like sports cars and watches or other tech gadgets etc.

Bill: Hey, did see that new Seiko 5 watch that came out yesterday?
Rudolph: No, I'm not a fan of watches.
Bill: Dude, it's one of the best entry watches right now. I'm definitely getting one.
Rudolph: Whatever blows your hair back, dude. Like I told you, I'm not a fan of watches.
