How To Change Day On Casio Calculator Watch

How to fix the time and date on a Casio CA-53 (with video and review)

Casio CA-53

I said I was going to buy this as ane of my nerdy purchases for 2017, and I did.

The Casio CA-53 is the de facto figurer sentry. In fact, whenever y'all hear "computer watch", Casio is the brand that immediately comes to listen. While Casio wasn't the start company to bring a calculator watch to market, they did do it best.

Before I become into the review of the watch, I fabricated a video on this watch explaining how to set the time, fix the alert, alter from 12-hour to 24-hour a.k.a. armed forces fourth dimension, and and so on. That video is below.

Hither are the main points of what'due south in the video in written class since this is what nearly people want to know near this particular model. If y'all don't understand any of these, watch the video below to encounter a visual example explained in plainer English.

Enabling or disabling the warning

Go to warning screen. Press 4.

Choosing AM or PM when setting the alarm

While setting the alarm time, printing the period key (every bit in the one with a tiny little "PM" side by side to it).

Enabling or disabling the hourly chime

Become to alarm screen. Press multiplication key (the one with the × next to information technology on the right side).

Enabling or disabling 24-hr a.k.a. military time

From main time screen, press adjust button (the recessed lesser silver button on the right side of the case). Press mode button (the argent button just higher up the recessed button) once to switch to adjusting the 60 minutes. Press the plus push button (the bottom right key).

Starting or stopping the stopwatch and resetting

Get to stopwatch screen. Press plus fundamental to offset. Printing over again to stop. To reset, press 0 (the bottom left key).

Viewing the year, calendar month and day

From the principal fourth dimension screen, press and hold the division key ÷ (the meridian right key).

Review of the CA-53

At start...

My initial impression of the watch one time I put information technology on the wrist was, "Wow, this thing isn't nearly equally nerdy as I idea it would be."

The funny thing about the CA-53 is that in pictures on a figurer screen, information technology looks like this unwieldy, oddly-shaped matter. In person, that's not the case at all. The watch actually has quite the sophisticated look to information technology. Yeah, seriously.

Compared to other Casio watches, the CA-53 is an exercise in restrained pattern. The but thing fifty-fifty remotely "loud" on it is the "WR" (Water Resist) gilt lettering at superlative right of the case. Everything else virtually it is subtle and purposely understated.

In a world full of digital wristwatches that look actually, actually tacky, the CA-53 is such a nice matter to see.

Readability

While the digits are really smaller than on the F-91W, the display is easy to read. Information technology can even exist read easily while wearing polarized sunglasses.

The lookout man does not have a backlight/nightlight, simply that doesn't bother me at all since I'g more interested in daytime and non nighttime reading. I take returned a few watches because of legibility bug in directly sunlight. And that even includes a few analog timepieces. The CA-53 can be read easily fifty-fifty under the brightest Florida sunday.

Functionality

Good, but not as easy as other Casio timepieces, for the reason things are not put in "Casio standard" locations. And because some features are outright subconscious unless you read the manual first. Almost of the hidden features not plainly marked on the watch are noted to a higher place and shown in the video below.

At that place are three more hidden features I didn't mention above or in the video beneath.

First is how to get a demonstration of the warning tone. When on the alarm screen, press 0 and + (bottom left and bottom correct keypad keys) at the same time and an alarm tone demo will audio.

Second is a characteristic that's not hidden but ambiguously marked. The stopwatch does in fact testify hours as information technology will go up to 23:59.99, but hours are not displayed on the stopwatch screen. The partition key ÷ (peak correct), also labeled "Date/ST-Hour", will show how many hours accept passed on the stopwatch screen if pressed and held. ST-Hour literally means "Stopwatch Hour".

Third is another stopwatch characteristic. The sentry will beep one time for every x minutes of stopwatch fourth dimension elapsed, but only when the stopwatch screen is selected. If you run the stopwatch, get out it running and go dorsum to the time screen, the beep will not audio every 10 minutes. This ways if you want to hear that 10-minute interval beep, stay on the stopwatch screen when the stopwatch is running.

Style

I actually similar the plainer, understated '80s style of the CA-53 and I absolutely have no problem wearing information technology in public.

For some reason in that location'southward this belief that when you wear a CA-53, anybody gawks and stares at y'all. That's non true at all. The just time people gawk and stare at a watch you're wearing is if it's something oversized and/or loud and/or tacky, and the CA-53 is the furthest thing from that.

Here are the actual measurements of the CA-53, and I took these myself:

Instance size side-to-side: 34mm
Case size side-to-side with push button included: 35mm
Case size diagonally measured: 43.5mm
Lug-to-lug: 42mm
Thickness: 8mm

The most misreported measurement is the thickness. Everywhere I've looked, the thickness is reported every bit 7mm. Non true. It's 8mm. If the "hump" on the back plate is omitted, then the measurement is 7mm. But that hump is what direct rests on the wrist, which when included adds up to 8mm.

Bated from that, the never-mentioned diagonal measurement is what takes people by surprise. The CA-53 is definitely rectangle shaped and so it is taller than it is wide. On the wrist, that makes for a good look. Smaller side-to-side compared to an F-91W, but too taller compared to an F-91W.

On my 6.75-inch size wrist, the CA-53 looks great. And I'd presume it would look skillful on a wrist size range of 6.5" to seven.25".

Sound

The beep tones of the CA-53 are what I believe to be unique to the watch. I'thou going to be using the F-91W every bit the comparing tone since that'southward the ane people know best.

Volume of the beep is not as loud as an F-91W, just nevertheless fairly audible.

Length of the beep is shorter than the F-91W.

Speed of the beep is a quicker stutter for alarm and hourly chime. The F-91W is a "BEEP BEEP" while the CA-53 is a "BEE-BEEP".

The total time an alarm will beep for is but like the F-91W, twenty seconds. The warning tin of course exist interrupted with a central printing.

Overall, the beep is a little quieter and definitely not as shrill as the F-91W'south beep.

Lastly I'll say this about Casio beep tones: The F-91W and steel version A158 take the loudest beeps. I own other newer Casio digital timepieces, and none of them have the book of the F-91W/A158. If you want a cheap Casio with a loud beep tone, you want an F-91W...

...and if yous tin can't hear the tone of an F-91W, and so I'd suggest the Casio W735H, a "Vibration Alarm" model. If your ears can't hear the beep tones, switch to something that vibrates the wrist instead. And before you enquire, no, it will non vibrate and then much to wake you from sleep. But information technology does vibrate enough to alert you when you're awake.

Comfort

The CA-53 is very comfortable. Very thin, lays flat on the wrist, very light in weight. Mine weighed in at 25g on my kitchen scale.

I tin can definitely say that you will accept absolutely no trouble pulling a shirt sleeve over the spotter, so yous can wear it with pretty much anything.

Immovability

I just got mine so I tin't actually say anything too much here. Simply I can say that this is a sentinel I don't plan on getting wet. Yes, the watch is technically water resistant, but all buttons added upwardly total to 18, meaning there's xviii different places water can enter.

What this basically means is other than an accidental light splash, this watch shouldn't get anywhere well-nigh water.

Yes, I know there are plenty of people who claim they've taken the CA-53 in the shower, gone swimming with information technology and then on, and the watch survived just fine. I personally would not do that.

Other than the water resistance or lack thereof, a known result with the CA-53 is the strap. It's soft, just sparse. Try not to pull on information technology likewise much when taking the watch on and off the wrist.

Happy?

I am happy to own the CA-53. There was a small learning bend just I figured everything out in a few minutes.

Will I ever use the estimator feature? Yeah. In fact, I surprised myself by using the figurer the first day I had it. I went to the grocery store to pick up a few items, and when I got dorsum to the parking lot I wanted to bank check the receipt to make certain all my items were added up properly. Usually I would catch my phone to do this math, simply I remembered I was wearing the CA-53 and thought I should endeavor using that, so I did.

Sure, the keypad buttons are small, but I was able to exercise my calculations. It worked!
