    impressive watch!

    This is the best watch on the planet! No exaggeration.It's affordable, waterproof, not flashy, and goes with just about every outfit. Whether I'm wearing jeans and a T-shirt or dressing up a little, it never looks out of place.I've actually bought this watch three different times. The first two times, I lost it after accidentally leaving it somewhere while I was out of town—not because the watch failed me! The third one lasted over two years, and I literally never took it off. It finally broke, but honestly, that was my fault after everything I put it through.It survived daily pool swimming, s

    Small, Lightweight and a Great Buy

    I really like this watch! It’s small, lightweight, and very comfortable to wear. It doesn’t feel bulky on my wrist, and it’s easy to wear every day. For the price, it’s definitely a good buy.

    Great option for kids!

    Very cute! It’s definitely not made for an adult, the face is tiny. It fits my 5 year old daughter perfectly though! Great color, seems durable, and the price was very reasonable. Would recommend for children (or small adults)!

    Quality

    I've bought the same watch for over a decade because of how many features this watch has and it's small size. I have tiny wrists so this one fits very nicely. The strap is adjustable with plenty of sizing options. There's a light feature, stopwatch, date (month, day, day of week) and time, and alarm. Can be set to military time as well. Very light weight and I always use it to check the date rather than my phone. I switched over to the gold version that is the same design since the strap of this one keeps breaking within 6 months time. Maybe it's just me but the resin strap last a year most fo

    Great for small wrists!

    I purchased this watch to replace an old smartwatch and to have something when I went camping. My wrist is a hair under 7" around and the watch is most comfortable on the 3rd to last hole where I have a little wiggle room. I looked at the other reviews before ordering and saw it runs small so I expected it to fit more like a petite watch.I went camping in July and we floated for about 9 hours. I was in and out of the water and was fully submerged a few times and the watch went with me. It was definitely waterproof! I was so happy it wasn't phased.I really do love this watch. It is minimal, not

    Really cute little watch

    My daughter loves it! It's dainty and pretty and easy to use, plus this thing will last forever. I had a ton of Casio's when I was little and it's been fun looking for watches with my own kids.

    Perfect for digital detox!

    It's perfect. Very light weight, I can't even tell it's on my wrist. Huge difference from my apple watch. Just what I needed to detox from being connected at all times. It has everything I need: the date, the time with seconds (Healthcare worker MUST HAVE), the ability to go between military and regular 12hr times, alarms, back light, and a stopwatch. It was smaller than I had expected when I opened it and for that, I am glad because I didn't want something super bulky. This is a 5/5+ for me. Definitely worth the money plus some.

    It's cute

    I like how small it is, it says it's for a child but I wear it all the time as a 30 year old lol, it's low some of its bubble gum pink color.
