It’s perfection!
9 October 2022Meaghan

originally posted on tillys.com

I searched high and low for the perfect watch, and I found it!I love everything about this watch—the durability of a G-shock, but in a smaller size. The color is beautiful, a soft turquoise color. The images on the website are true to the color. I’m an average size female with barely size 6” wrists and this watch fits perfectly, and doesn’t feel oversized on my wrist. I needed the instructions to set the watch, but they were easy to understand. And the hands glow in the dark!

Nice everyday watch, complicated settings

The watch is really pretty, and has all the great features of gshock. It definitely took some practice to understand how to change the time, day, date, etc. The instructions didn't help me, but there are a couple of videos of YouTube that are really helpful, if you search by the watch's model name. Otherwise, the strap has a lot of holes for smaller wrists, and the watch looks great. It is more of a casual watch, but because of the black and wine color, it may look ok in a semi formal setting too!
