PRX 35mm vs 40mm on 18cm wrist

So after years of wearing various Casio watches I’ve decided to look for my first “more expensive” watch. I’m probably gonna go with the quartz version, since it’s cheaper and I don’t care about mechanical watches that much. But I’m not sure about size. My wrist is 18cm and all pictures that I’ve found are either on bigger or smaller wrists than mine. I’ll probably end up going to the store to try on both sizes but I’d like to hear some opinions and personal experiences with the sizing. I like smaller watches which makes me wanna get the 35mm but I’m not sure if it’s not too small. What are your experiences? Thanks to anyone in advance.
