Like an Apple Watch Only Not
by Ethan (4 out of 5 stars)
January 30, 2015

I've always wanted a calculator watch. Now that I'm pushing 30, I felt that I'm an adult and I can do what I want and I want to buy a calculator watch, dammit. Yeah, I said it. You're not my mom. Deal with it.

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.

It's just as awesome as you expect it to be. Classic Casio!

What a cool piece. I'm 33, so I'm just old enough to remember this watch being the coolest thing in the mid 80s, then progress to something only nerds and dorks would wear, then fade into obscurity. But since it's now 2017 and it's cool to be a geek again, this is now so nerdy it's awesome. I put it on a cool NATO style strap, and this watch gets as many compliments and is as fun to wear as my nice, conventional watches. It's the best style statement you can make for 17 bucks.

Functionality wise, it's awesome. Calculator, stopwatch, and dual time zones. No backlight, however. But overall, what a quality piece. I love it!

The Best Watch
by mia (5 out of 5 stars)
July 5, 2017

this is literally the best watch. ever. no debate there. i've worn it every single day since i bought it 10 months ago and it still brings me immense joy whenever i look down at it. the functions are relatively easy to use and it's durable and secure. i adore this watch and get a LOT of compliments about it, because, y'know, calculator watches are literally the best thing to ever be created by mankind, if not the only good thing. i absolutely recommend this glorious watch. it has gotten me through dark times and helps me calculate tax in even the most difficult situations. also, it's really fun to make it say "8008135" and then show it to my friends and family. you would think that would get old after 10 months straight but it's still hilarious and nobody can tell me otherwise. if you want a high-quality, affordable, and surprisingly entertaining timepiece, my professional opinion is BUY THIS WATCH. you will NOT regret it.

Casio CA53W Calculator Watch Review
by G. Teruya (5 out of 5 stars)
May 15, 2016

This is a review of the Casio CA53W Calculator Watch. Back in primary school in the 80's, this was one of the watches that everyone wanted to own. Since I was more active with sports and swimming, my parents only got me a Casio that was 100M water resistant or more. Close to 30 years later, I am finally able to fulfill this desire. It does so in great success.

Features:
- 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.
- Alarm.
- 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.

I'm a pretty heavy user
by Peckl (5 out of 5 stars)

I first used this watch on my first Pacific crossing as a Captain on a B-747-400 in 1989. It has made many crossings: Teipei; Honkong; Manila; NRT; BOK; SYD; AKL; et.al. I have used it for fuel calculations verifying company generated flight plans. Used it crossing the Atlantic to Heathrow, then on to New Dehli. Water calculations, too, adding water ballast for sailplane racing. 1 gallon weighs 8.33#. My ship carries up to 50 gallons. I have probably bought 20-30, using them for gifts. Sometimes right off my wrist. Bands tend to break for me after several years. I'm a pretty heavy user. Now for sailing, I reach down to clean milfoil off my rudder. One leaked, but works fine after drying it out for an hour or two. I keep that one for dry land use, only. Though, it is hard to tell them apart after you clean the buttons with a tooth brush. I always keep an extra two or three in my chest of drawers. I give it 10 out of 10 stars. I fear the day they go out of production✈️🎌〰.

The best inexpensive watch you can spend your money on.
by Phil McKrevice (5 out of 5 stars)
December 21, 2017

This is my 2nd watch. The part that holds the excess wrist strap down broke, but the band itself is fine. Unable to find another band, I just opted to buy a whole new watch for 16 bucks. My first watch was purchased in December of 2012. It is now December 2017, and it is still working with that same battery. I have no idea how long the watch was running when I bought it, but I would say that 5 years out of the battery is normal.

This watch is great. It is light enough that I do not feel the need to take it off. It is water proof for the things I do...occasional swimming and I leave it on when I shower. I have hit this watch on numerous things like counters and it has taken a beating and the watch is without scratches and works just as good as the day I bought it. This watch can take a beating. I wish that it had a light, but that's my only thing that I would change. And this watch gets people's attention if that's your thing. I have never had so many people make comments about how cool it is, and I have some pretty nice watches. This thing has received at least 10 times more comments than all of my other watches combined. The nice thing is that I never have to worry about someone trying to steal it, as opposed to my other watches. I like the look. I like the price. I have nothing bad to say about this little watch. If you are like me and grew up in the 80's, always wanted one of these watches but did not get because they were so expensive back then, I highly recommend this. Especially if you travel to the Caribbean via cruise ship and need a good watch to go swimming with, but not want to draw too much attention to yourself and to make sure you get back to your ship in time.

Out with the New, In with the Retro!
by Dave,Top Contributor: Baby (5 out of 5 stars)

Wish this watch could calculate cos and sin and exponential powers.... jk. I am not that smart and this helps me add and subtract when I run out of fingers and toes to count with. It also has a retro look to it that I think matches my personality. I get compliments on it all the time. I am use to wearing g-shock watches so was worried about the durability of this watch. However, after wearing the watch for over 4 months, I can attest that this watch not only looks nice, but is built well. I also have a newborn and I like how it doesn't always "bonk" against my son's head since it is low-profile (my g-shock had a big watch head and would constantly hit against my son's head).

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 :)

Buy it now before it goes out of style.
by Quiltface (4 out of 5 stars)

Great watch, it tells time. It has a calculator. it has the day of the week. It has a whole other time zone. It has a stop watch, which I have yet to really use. An alarm... that I tested and it actually woke me up. Surprisingly the buttons are not hard to press, while running the calculator I have not yet hit a wrong button. 12h/24h time format option. And its not bulky
4 stars and this is why not 5.
#1 It needs a back light
#2 The strap could be a little bigger/better
#3 It should come with a stick to help fight off all the ladies that will want you to buy them things because they think you are rich.

To NATO Strap users: Beware!
by Andrew (5 out of 5 stars)
April 15, 2019

The watch is exactly what I expected it to be. The same thing I used when I was a kid. 5 star.

Just know this thing has no backlight.

However, to anyone buying this based off the fact that user reviews show it on NATO bands: It is a seriously tight squeeze.

I bought this with the intention of putting it on a 18mm NATO band, so I was fiercely determined. But, I was pretty much convinced I was going to break the watch attempting to get it on, and am still pretty convinced it will eventually break considering the watch is plastic and the amount of force I had to use to get the pins in place.

I would reconsider if you are intending to use nato bands, or make sure you find the thinnest ones available. Also, be prepared to fight them on.
