Review: Still going strong - Nice Casio quality.
Review: Super durable and cute - This watch is incredibly durable and long lasting. I am extremely tough on things because I like to adventure a lot. This watch, however, is able to withstand what I do to it. It has been swimming and diving with me in chlorinated pools, lakes, rivers, and in the ocean. It also has been banged on rocks, trees, and door frames because I often forget where my arms are in space if I am too busy concentrating on other things. So for the durability aspect of this product I am extremely pleased with it. I am also very happy with how this product looks. It is pretty feminine and small, so I still feel like a girl while wearing this heavy duty watch. I like the color and display as well. It is very convenient to be able to read it at a glance and get the date, time, and day of the week. I also enjoy the alarm setting and the user-ability. I hate reading manuals and this watch was really easy to set and further program by just messing around with it. Casio makes a good product, and I am really happy with what I got with this watch for the price of it. Although I have not used the lap and other running modes to this watch, it's cool they are there because I like to use the stopwatch on it for cooking/baking. Overall I am very pleased with the durability, looks, and function of the watch as well as the battery life on it. I would definitely buy this watch again if I ever were to do something bad enough to it that it broke (yet that isn't very likely).

## Questions & Answers

**Q: Can someone please guide me how to off the alarm? Lost the manual and can't find it online! Thank you!**
A: http://ftp.casio.co.jp/pub/world_manual/wat/en/qw2575.pdf   Hello, this is the manual. Alarm always turns to default 12:00

**Q: Is the band one piece?  Does it slip through behind the watch back?  Skin sensitivity to metal contact.**
A: The back of the watch is stainless steel and it will be touching your skin once on your wrist.

**Q: Ok...this might be a silly question.  I know it says running watch.  My question is will it count steps while I walk?**
A: No... It lets you time laps,  or miles,  or times between two points.  Step counters are just "estimaters" usually not accurate.  So,  say you measure out a mile and you run that in 10 minutes.  If you measure your running stride (say for example 8 strides in 20 feet running at your normal pace) that would be 30 inches.  With 15,360 inches in a mile you would have 512 "steps" or "paces."  You also will have to correct for walking,  shorter strides, and step counters treat all steps the same even if you move 10 inches,  shorter than a walking stride.

**Q: Is there an option to remove the year from the display? Or to add a P or A (for pm or am)?**
A: Yes, you can remove the date, however you cannot add 'am' or 'pm'.  You do have an option to set it to military time, though.

### ⭐⭐⭐⭐⭐ My favorite watch EVER!
*by J***N on December 10, 2025*

I’m so very happy with this watch. I love the black and purple color scheme, though a couple other colors are available. There are six different screens. The main screen has the time and date, including the day and year. The time can be set to 12- or 24-hour time. There is a stopwatch, which, in addition to standard uses, lets me learn actual time for tasks that I do, keeping my optimism in check! The stopwatch times are automatically saved, but can easily be deleted. There is a countdown timer which, once set, remembers the length of time set. This is another one of my favorite features, as it allows for repeated intervals without having to re-enter the amount of time. The watch can be set to beep on the hour, and there are five separate alarms, which can really help with time management. There is a screen for a second time, in case you need to keep track of the time in a different time zone. Most of the screens show the current time at the bottom. When scrolling through the screens, there is a beep. At the return to the main time screen, the beep is at a higher pitch. All these features make this my favorite watch ever! It’s still running strong after 8 years, though the band just recently broke off the pin. I replaced it with a BISONSTRAP 16mm silicone watch band, and, to my surprise, I love it even more! The new strap is of a uniform width and thickness, whereas the original band became wider and thicker at the watch face. This means that the new band leaves easy-grip edges for readjusting the watch on my wrist. The original band was stiff and curved, so when I took off the watch, it lay on its side. The new band is soft and flexible, which allows the watch to lay flat on a table when not being worn. If I like, I can put the buckle prong into one of the holes in the strap, and the watch will sit on the table like a little clock!
