Expensive luxury items are basically "worth it" if you think they are. No one needs them, whether it be an expensive car/boat/watch/you name it but the desire for them fuels the economy. I've never worn an expensive watch because my dad did not wear a watch at all, (or any other jewelry), even though he spent $$ on other things like schit through a goose.
I'm a $40 Timex guy because I like knowing what time it is without constantly looking at my iPhone. I spend $$ on restaurant meals in a way that many here would consider insane if they eat always at home. I always find it interesting the way that people choose to spend their $$, not everyone likes or cares about the same things.
If it makes you happy, go for it. Life is short.
