CasioWith the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward. See more

FOR THE PRICE, AN EXCELLENT CHOICE FOR A CHRONOGRAPH WATCH...
Although I purchased this watch for $11 less during the 1st quarter of 2023, I would still recommend it for someone who wants a quality multifunction chronograph for a relatively low purchase price.I'm not very fond of bracelet watch bands, so I immediately replaced it with a quick release palamino tan leather watch band. With the black dial, it would have the proper aesthetic contrast with just about any color leather watch band. Mine looks spectacular.Most chronographs at this price point do not feature a 1/20th second stop watch feature. This watch has that. Another exceptional feature is the second hand reset hack. Each time you completely extend the stem, the second hand zeros out.For those of you who have learned how to utilize a slide rule, this watch features one that is functional and attractive with the stem located at the 08:00 position.It does pay, in the long run, to disengage the watch mechanism when storing it. It does save the battery. I stored a watch for 4 years without using it and when re-engaged, the battery had plenty of energy left.Sturdy, accurate, and attractive...this CASIO Edifice watch is a bargain at the current price.

An amazing value for the money!
As a collector with watches ranging from Swatch models, Citizens (mid-tier), Seiko models ranging from entry Seiko 5's, to a few Prospex, Presages, and one GS, several Orient models, and of course three Timex models, I have to chuckle at the value for money you get with many Casio watches. I have six altogether with this purchase and they really do nail the fundamentals.The bracelet is inline with the quality you would find on some Seiko models costing three times as much. Yes, it's a bit flimsy and light making a song of its own when you put the watch on or take it off, but at this price point, it's a very well made bracelet overall and aesthetically pleasing to be sure. With a mixture of brushed and polished edges, the oyster bracelet (with a hint of engineer style center links) is very attractive as is the watch entirely. And it's a cinch to adjust the links. No pin and collar system, just friction pins.As a few have mentioned, the watch looks MUCH more expensive than it is and it's a perfect weight as well. The case design is definitely unique between the lugs. A polished and brushed lip accenting the bezel and dial. It's something unique to this watch out of the forty-five I have in my collection. A small detail but one that made me smile.The lume isn't stellar as far as brightness goes, but it is sufficient and it lasts a decent amount of time. It's a pleasing turquoise blue. Similar to a few of my Citizen's, though not quite as bright.100 meters water resistance and I would be confident in that with the watch's screw down crown. Another feature not always found on watches costing much more. Suitable for swimming of course, but do NOT depress the pushers while underwater. I would also never shower with ANY of my watches regardless of their rating. Hot shower water (or any extended exposure to heated water) and the cooler air found inside of the watch are not a good combination. It's senseless to shower with a watch in any case. Ocean and pool water are what they're designed for.I'm not sure what processes Casio uses to sell watches at the prices they do, but I'm glad I've been able to benefit from it. As many others have. This watch could easily be sold for $150 more than the price I paid and would be worth it.Very pleased with this purchase!

Muy bonito reloj. No pesa mucho. Llegó una semana antes de lo indicado. Comparandolo con un Seiko, si a Seiko como referencia le pongo un 20/20 a este reloj le pongo un 17/20.

Those who have it one star....
Read the direction. Granted, Casio should have highlighted that this particularodel's watch crown MUST be unscrewed BEFORE you can reset the date and time. Then screw the crown BACK in before exposing it to water!!!! Because if you try and force it BEFORE unscrewing the crown, you could break it! Casio you need to put s red tag on the watch band to highlight this, if you are going to put generic instructions into the case.

Fantastic Value, Fantastic Watch; One Caveat
Update:I noticed that some of the other reviewers had an issue with the accuracy of the slide rule, so I decided to check mine closely with several calculations. Mine was the same, very slightly inaccurate. Multiplying 30X40, as one other reviewer did, yielded a result of 1210 on my watch. An error of just under 1%, but an error nonetheless. The question then becomes: how important is that margin of error (especially once you know it exists and can account for it). In my case, it matters very little. But I only use the watch for quick estimates. True, my Seiko is dead-on accurate. But it is also far less legible for me. The customer will have to decide for themselves if this watch will suit their specific needs. In any case, I still think the build, heft, good functionality, and overall presence of the watch far exceed its price. It is still a great value.Original Review:This watch is impressive; it rivals any in my collection. It is large, very legible, and incredibly well-made. It looks far more expensive than it is. You will probably want to change the band. I did, tried a bunch, but found it popped with a brown and black NATO style band. This one is from Bertucci. One piece of advice: buy an E6B flight computer to learn how to use the circular slide rule (all slide rule watches are based on this ingenious device, $10-$30). The functionality of the watch will be far more fun.

One of the best
I've owned this watch for 10 years, and it’s hands down one of the best I’ve ever had. The sapphire glass is incredibly durable—after all these years and plenty of bumps, there's not a single scratch on it. Casio truly stands at the top for quality!
