A Perfect Blend
I have 2 other Casio Gshocks and it is definitely a great watch. The look of this one is such a perfect blend of feminine, sporty, fashionable and functional. I absolutely love the rose gold details, they give it a cute, feminine touch. I’m not usually one to wear pink, but this watch is such a subtle pink it’s really nice. I would highly recommend this watch for someone who wants functional and durable with a cute style! ... show more

Pink Perfection
I believe this is the nicest watch that I have ever owned. It is absolutely so soft and elegant, somehow as it maintains its casual sportiness. The pink and rose gold tones are absolute perfection. I love watches and I am so excited to have this one. After being in both Fitbit and Apple Watches for about 4-5 years, I was just tired of the constant notifications and pressure on step quotas. Was also tired of looking at my wrist and seeing a dark screen that I had to activate. So glad I went back to a traditional watch. Very excited and my time management has already improved as well. Anyway, this watch is gorgeous, you will not be disappointed!!!! ... show more

Not gshock quality
Great but it squeaks when I move my wrist. No matter how loose it is unless it’s loose enough to be a bracelet. It’s the plastic around the face. Def not typical GShock quality. 4 stars cuz I love it otherwise. Everything works as it should.

Perfect travel/outdoor watch, love it more than I anticipated
Needed a reliable travel watch that I can swim, shower, do physical activities in, and one that doesn’t look ostentatious when visiting a variety of locales. This g-shock fits the bill 100%, I take it on all my travels and outdoor adventures. When changing timezones, setting time is a breeze. Nothing bad to say about this watch, it’s simply awesome. ... show more
