Beautiful Watch, and easy to set up.
Color: 5535-ZP-blue
Looks classy, very easy to set the time, day of the week, and date. It is a class cover so it can break if dropped (my kids broke my first one), but it's inexpensive so it wasn't a huge deal. It's easy to read. Battery hasn't died for months. It's easy to put on and the size works for me.

Runs like a Rolex
Color: 5535-ZP-blue
What a watch!! A very nice watch. Everyone asks if it is a Rolex!! I say NO but it keeps me on time like a Timex. The band is wearing a little quickly but otherwise thumbs up!

Most important review for this watch and company.
Color: 5566-ZP-blue face, Color: 5566-ZP-blue face
I bought two and they both broke. Customer service has ignored my e-mail. What more do you need to know about a company? I personally wrote them through their own website, so they could keep Amazon out of it. It makes me angry that they won't even reply to my e-mail. I was nice. Both watches broke, neither one if actually water proof. The band is exceptionally thin and it WILL break on you once it arrives. It's so poor, that my body moisture is what got into the face of the watch. What the heck? I've had better 9 dollar watches from Walmart. Zero out of zero for the COMPANY who doesn't care about their customers, and zero out of ten for watch quality. Useless. I wasted 60-80 bucks on two of these! BOTH BROKE! and in more than one way!!!!! Terribly marked up (this is less than a 10 dollar Walmart watch - quality is LOWER than the lowest 3 dollar watches off Temu, Shien, Walmart), customer service is non-existent, and the band WILL BREAK on you. It's worthless. Take your money somewhere else. Attached pictures show the moisture leak from my sweat, but in real life, it's actually much worse. Worthless, not usable. Two of them folks. TWO!

As Advertised
Color: 5535-HP-white
The watch is what I expected, and works upon receipt as advertised. At this price, if it only works for 4-6 months it's easily worth the money. Large, nice looking face, day/date. Wristband is what you'd expect, but adequate and comfortable.
