Casio AE1500 One-Month Accuracy Results

I have six AE-1500 watches and, about a month ago, I synchronized them all to "atomic time". According to Casio, these watches should stay accurate to plus-or-minus 30 seconds per month. After 29 days I looked at all six watches to see how accurate they were. Although they all have Casio's Module 3502 their accuracy was not exactly the same. Two of them were running a few seconds slow. The other four were running a few seconds fast. But all of them were still within plus-or-minus 30 seconds of the exact, correct "atomic time" in the end.

The Casio AE1500 is a great value at only about $20 - $30 right now, depending on where you shop. (The list price from Casio tops out at $30.) It has a large LCD screen with the largest digits of any Casio watch I own. It would make a great watch for someone who has special needs with regard to vision. In addition to its normal timekeeping it has five alarms (one of which is a "Snooze" alarm), an hourly chime, a 24-hour countdown timer with an auto-repeat option, a 24-hour stopwatch and a Dual Time mode. The watch can be set to a 12-hour or 24-hour display for all modes. It is water resistant to 100 meters and it can run for up to 10 years on a common CR2032 lithium battery. Detailed instructions are available for download from Casio's website. Just look for module 3502.

My favorite beater watch of all time. I have the khaki one. Mine is off by < 15 seconds per month, but if I do not adjust it for a long time, the average per month tends to be even better, so perhaps based on how I use it, swim, walk, expose to Florida sun, etc., it varies slightly, faster and slower. Overall, the watch is brilliant, particularly when you consider the price.

@@jobnewton2152 "15 seconds per month is not good" -- With variations I have discussed earlier, it would likely be < 1 min per 6 months. I can live with that on a beater, and I adjust it around that interval.

Greg Anderson. Thanks for the video. I have a hard time with 10 watches....you have 100?? Wow I would love to see them.😊

One of the better Casio watches. Really enjoy wearing it

[@PapriceP]

This is one Casio reference where the negative display is very legible.

[@user-gk4jd1jv4k]

Quite a few of them are to me although I hear this complaint often!!!???

[@SuperMrgentleman]

I think the temperature variation from wearing or not wearing the watch can matter on a small scale. Various high accuracy quartz watches use thermocompensation to try and adjust for this, but many also stipulate their claimed accuracies of 5 seconds a year or whatever can only be achieved if the watch is worn for X hours a day. I feel like if it didn't matter then HAQs wouldn't need to stipulate that.

Glad you got a video out. It's been a long while. I miss you guy

I have my G-Shock squares set up the same way. And now you have me planning on doing my own accuracy test starting September 1. 😅

[@pauljosephbuggle3722]

Very impressive. I only use quartz watches, mostly Casios. It just makes sense.

Finally got my g-shock I been wanting for about two years the all steel square silver. I wear it every day

Good to see you back...

[@GoodTimekeeper]

Good to be back. I spent a lot of time with family and got a few other projects done this summer but now I am having a bit more time to devote to The Good Timekeeping Show (with Greg Anderson). Maybe I need to find a fill-in host who isn’t busy right now. Imagine The Good Timekeeping Show with Seth Meyers. Or… maybe not.

[@taiguy4961]

Makes sense now as to why they jump the minute up one if the seconds is after 30. With a +/- 30 second a month accuracy, setting Your watch to exact once a month can be done with one press of the adjustment button as it will always be jumped up or back down to the correct minute.

[@marcelovasconcellos6067]

Great video. As it happens I’m carrying out my own little month long accuracy test of all my Casios and my green AE-1500 with the extra long strap is seemingly doing pretty good. BTW another 1500 that might interest you is the WS-1500H. Great watch with design similar to the AE-1500 but with a lot more features like fishing data, moon phase and a liquid crystal analog display that is bigger than say on the Royale and as a first I believe for Casio has cool animations on it according to what mode you’re in. Apparently the module is brand new and exclusive to the WS-1500H which is a 2023 release. Around 30 bucks in the US I believe.

I just picked up a blue one from Argos yesterday. I did have an Apple Watch before but was fairly useless on my wrist & got sick of charging it every day & now i dont need to worry about it for an entire decade... No competition! 🥰

[@grahamdwells]

Dude this is an intervention... You have an addiction to the AE1500. Yes it is a lovely watch but enough is enough.

[@PapriceP]

You have several Casios. Can you make a video on the subject of resin rot?

I was wondering why the battery runs so fast on the time, because it does, and I’m shocked that my now own W737H can’t even catch up to it, dang! 😆😆😆

[@sylvainster30]

The last G-shock I got is the Nasa 6900 the white one….it’s going +3 sec per week so roughly 12 sec a month, not bad I guess! ✌🏼😎👍🏼

[@DanRC69]

That seems a LOT for a G-Shock, they are usually considerably more accurate than that.

[@sylvainster30]

@@DanRC69 Really? I have 16 G-Shocks and the only ones that are really accurate are the atomic models and I have 1 GA700 that gains +1 sec a month….I set that one in January and its 8 sec off, that is a fluke because all the others are +3 to +5 sec a week

[@DanRC69]

@sylvainster30 I've got a GBX100 that after around 6 months is only +1 second (with bluetooth OFF) over my atomic 5600 which is amazing, my GA2110U is only about +7 seconds over the same time, gbd800 (never wear it though - uncomfortable) at about +14s, so all perfectly good.

[@mikeyblueeyes8449]

[@BagoGarde]

a great watch for a daily beater

[@tylovset]

Could be interesting to see the accuracy differences of each watch from month to month (or week to week). From my limited testing it is very consistent. If so, why wouldn't casio just add a speed offset option to be set by the user? Any watch could then be accurate to a few seconds a year. Then again, probably not good business for casio, in relation to the auto syncing models.

[@GoodTimekeeper]

I suppose they just wanted to make sure they kept this as a very low-priced watch. Not super fancy but a great value.

[@roadgent7921]

Casio used to put trimmer capacitors in virtually all their watches. Quite rare now though. Which is a pity. My older 690, 901 and 1199 modules I've trimmed to 1 sec a month without too much effort. 😊

Nice video. I don't know about this test but my 2 year old AE1500 that I wear daily, loses 3 to 4 seconds in 6 months. Maybe I got a good batch watch, who knows...

[@montecri]

Quartz watches are affected by temperature. It is possible that they are factory-calibrated to the human body temperature. If that's the case, they will run more accurately while worn.

[@5843zman]

Have you tried the new White band with negative display yet ? Mine has stayed on atomic time correctly 5 days straight. Maybe Casio changed the newer models some ?

My Casio F-91W is fast 2-3 seconds per month.

[@yambo59]

considering I paid $20 for mine new im not going to complain one bit about this kind of accuracy - much like computer chips in computers you play the IC lottery, each one slightly different but still well within specs and beats many high dollar mechanical watches thqt run slower as the mainspring runs down and or it needs an expensive service. For me a decent quartz watch makes a lot more sense function wise than a $$$$$ Rolex thats more fragile when dropped and will need a very expensive service periodically to keep it within specs that often arent as good as a decent quartz watch..

Nope. It's the most accurate one. All others are 12 hours off.

[@DanRC69]

Some are just not set to 24H mode.

[@DanRC69]

All of my G-Shocks (except multiband) probably gain between 1 and 3 seconds a month, so i guess the cheapest Casio's aren't as accurate as i was expecting. Still - nothing a monthly sync couldn't sort.

[@ElliottVeares]

Their quartz crystal watches right? If so, that's atrocious time keeping, I would expect them all to be within a second or two of each other a year later, let alone a month later!

[@DanRC69]

I agree, my Casio's (mostly G-Shocks) gain considerably less in a WHOLE year.
