It's great. It has dual time, a stopwatch, alarm, tells the date and day of the week, AND A FRIGGIN' CALCULATOR. If you wear it tightly enough, you can feel your pulse. So it's like an Apple Watch only it costs under $20, has a 3 year manufacturer's warranty, and the battery lasts five years. Doesn't send text messages, but you can write such words as 'BOOBS', 'BOOBIES', 'BOOBLESS', 'BEES', and 'SHOE'. So if you're a man of few words and your friend is right next to you, it's basically the same as iMessage.
Knocked off a star because the screen seems to lack some contrast. Not sure if it's permanent or the battery is low. Can't recharge the battery, so I don't know.
Functionality wise, it's awesome. Calculator, stopwatch, and dual time zones. No backlight, however. But overall, what a quality piece. I love it!
- Time with hours, minutes, and seconds. Also displayed on the main screen are the AM/PM indicator and the day of the week.
- Basic calculator.
- Dual time zone.
- Stop watch.
Wishes to add to this watch:
- Electroluminescent display.
- At least 50M water resistance.
This would be the perfect watch with an electroluminescent display and at least 50M of water resistance. Other than that, I am completely pleased with this watch as it fulfills that vintage charm, has so many features, and has a very attractive and symmetrical display. Best of all, I am glad to have this one after finding out on the Casio website that this is being discontinued. A 4.5 out of 5.0 stars.
UPDATE July 11, 2016:
Attached are pictures of the Casio CA53W Calculator Watch compared to couple of affordable alternatives that are also from Casio, the Casio W800H-1AV ($12) and the Casio F105W-1A ($13). I wish the Calculator Watch had the Electroluminescent light of the F105W, which is the most attractive watch light in my experience. The F105W is just too small for my wrist, though the Calculator Watch is the perfect size.
Don't expect to be able to calculate and figure out dark matter with this watch, but wearing it makes you look like you could :)
Upon first purchasing the watch, I felt that I would mostly just use it as a fashion statement more or less -- some kind of geek hipster I guess. But I use this thing all the time: Tips on food, BitCoin conversions, tallying my PostMates delivery totals, all kinds of daily math! I have a genuine need for the second time zone too, having relatives and family in another country and I use the stopwatch frequently to time things like workouts and bike rides as well as walking times to all the facilities I use on a daily basis so that I can find the fastest routes (I'm a big nerd, I know). I probably use this watch for something other than telling time around 10 times a day.
I have an iPhone and, sure, I could do all the same things on the iPhone and more than this cheap little watch, but the watch is right there on my wrist! I don't have to take it out, unlock it, and find whatever app I need to use, I just turn my wrist and get straight into it. Sure, I could get an Apple Watch, but I don't see the need to spend $350 on what is essentially a second phone at this point in my life and many of the same problems that come from the complexity of so much versatility would still get in the way. And I can't imagine what using a calculator with such a tiny touch-screen would be like. Even if they're tiny, the Casio's buttons are physical, which goes a long way to being easy to press.
If you are a fan of calculators, geeky things, cheap useful things, or Back to the Future and Marty McFly don't hesitate.
This watch is fantastic. Casio was way ahead of their time in the late 70s and 80s, not with just this watch but all the fitness and calculator watches they produced. This is an icon of an era of extreme leaps in personal computing technology.
* Watch (either 12 or 24 hour) with day of the week indicator and toggle to see year, month and day
* Basic Calculator supporting up to 8 digits and supporting addition, subtraction, multiplication and division, as well as basic exponents
* Alarm (can also set an hourly chime from here)
* Alternate timezone
* Stopwatch: chimes every 10 minutes, can record multiple laps.
+ 5 functions: Clock, Calculator, Alarm, Alternate Timezone, Stopwatch
+ Option to have watch chime on the hour
+ Can technically multitask (run the stopwatch in the background while you use other functions)
+ Durable and Water Resistent
+ Alarm is a good volume
+ Keeps precise time (I synced it to time.gov several days ago and it's still accurate to the precise second)
+ Because of it's simplicity, it just works
+ Surprisingly feature-full for such simple technology.
- I personally wish the holes in the arm band were offset 50%. One hole is slightly too tight and the next is slightly too lose. That's just a nit-picky personal problem though.
