Solid watch for the price
I have numerous nicer watches and often times I find myself wearing my Casio instead. The dial looks very striking for such an inexpensive watch and you don’t need to wind it so it always keeps time. The brushed metal looks very nice too. It’s pretty light weight and fits my wrist fine although I had to remove links when I got it. It’s also very easy to read. Would recommend

Very nice watch
Nice watch. Took me 5 mins to adjust the watch wrist, not bad at all, go watch YouTube if you don’t know how to adjust the wrist, very easy.
