They’re very good inexpensive watches

One of the best with affordability and quality ratio. I'd say them and Timex are fairly close with that particular market. Nearly every "watch collector" I know has one of each.
Casio and Timex are the perfect brands if you're not a watch guy. They're objectively more accurate watches than most Rolexes, they look good, they're affordable, and people who ARE watch guys won't look at a Casio and say "lol noob," they'll look at a Casio and say "ah, this guy knows his watches, he's just wearing his beater watch today."
Watch guys who spend a bazillion dollars on watches basically fixate on two things--one of them is the brand name (though we don't have many of those in the subreddit), and the other is the movement. Most Casio watches use a quartz movement, which is the least expensive movement and also keeps the best time, and it has the fewest moving parts.
High end watches frequently have automatic or hand-winding movements, which don't run on batteries and keep time using an intricate network of gears and springs, all working together in perfect harmony. There is absolutely a certain fascinating joy that comes from wearing one of these tiny intricate clockwork mechanisms on your wrist.
That said, these watches aren't cheap, good ones even less so--and automatic and hand-winding movements are usually the biggest difference maker that sets a "cheap" watch apart from a "fancy" watch. Your Casio is a "cheap" watch in part because it uses a quartz movement--but like I said, a quartz movement actually keeps better time, so no watch guy is going to shame you for wearing one.
