### ⭐⭐⭐⭐⭐ Casio really knocked it out of the park.
*by A***R on October 10, 2023*

I've been a fan of g-shock watches for a long time but I won't deny a lot of them don't fit my personal fashion choices. I have skinny wrists so probably 90% of them are too large for me. Plus I work in an office most days and have to wear something that looks a bit nicer than the rugged appearance of the typical g-shock. So with all that said, this watch really ticks a lot of boxes for me. Yes, I would agree with some reviews here that the design choices do sacrifice the functionality at times. The LCD is small and the "stealth" looks of the all black model does affect the legibility. But having the ability to wear a g-shock with a suit makes it all worth it for me. I still find the watch plenty easy to read at a glance. I have found that this watch is especially well suited for travel. It's a good all around look for a variety of business casual outfits and looks equally at home in the board room as it does networking at a local restaurant. It's more than rugged enough to stand up to airports and taxi cabs and the alarms give me a little extra assurance when I need to get up early but I'm thrown off being in a new time zone. I am very pleased with this watch. If legibility is your top concern, there are variations of the "casio oak" that might be better suited for you. For me, having the all black look was worth some small sacrifices and I absolutely knew that was going to be the case when I bought it.
