You got the wrong watch. 
Watches don’t have to be flashy or clunky.
What about a Nomos Orion for example? It’s unpretentious, very flat (just 8,7mm), slender, and automatic. I like most Nomos watches exactly because they’re not flashy but very modest.
I own watches because I like them, not because I want to impress someone. Most people don’t notice what kind of watch you wear.
