Casio was founded in Japan in 1946, and in 1957 the brand was introduced to the rest of the world based on their invention of the world's first electronic calculator. The technology behind the electronic calculator became the foundation for the digital watches of the future. Casio watches already saw the light of day in the 1980s, and up through the 90s Casio was established as the leading brand in the digital watch market. Casio's digital watches quickly became popular around the world.

Better to go in a real shop!

Needed to call for an update. Still haven't know when they dispach the item. And using Parcelforce? Is this a joke? Still no watch as they failed to deliver, scanned the item on a different address. No watch no birthday present. Thank you to using a useless delivery service for a 350 watch.

Bought for the add ins but quickly returned

I bought this watch for the add ons… barometer with temperature, digital compass and altimeter.I tested them out of the box and all three were inaccurate, but it says try it outside away from walls etc, so I took it to a remote field to test….Temp was +10cAltimeter was 100m outCompass was no where nearI judged it against a number of other references and it just didn’t deliver the accuracy it needs to justify the high cost.Real shame as this is a good looking watch, so if you can see past everything else at least you’d have a nice watch that can tell the time. (Time was accurate)

Decent quality however couple of things…

Di not get me wrong. It is a great watch, good quality as you can expect. Two things: the display is dark amd it is hard to read it, not as in pictures. Second thing, the orange/red is neither red or orange rather karmin (maybe) like.

Fantastic watch with great functionality,
19 August 2023

Fantastic watch with great functionality, my only gripe with this watch is the display, in some conditions its awkward to read , other than that I'm happy with my purchases of yet another G shock

Watch arrived in a timely fashion from Casio . Disappointed with the watch face which appears to be very dark and difficult to see the watch face

Nice watch
23 August 2023

Couldn't decide on the negative display but decided to go for it, works very well and can see it the screen in most lighting conditions, a twist of the wrist normally helps, love the quality of these watches and have not took it off since buying it, as mentioned the negative display can be a deal-breaker for some but personally I like it

Poor display
12 August 2023

Beautiful watch and in direct sunlight the display is really clear, however once indoors and in a normal lit room it is really hard to see the numbers.

Poor display lets watch down.
30 August 2023

Lovely looking watch and felt as tough as old boots. Unfortunately, I found I was unable to see the screen display in most light conditions without pressing the light button. At £350, this is an unacceptable design flaw so I returned the watch as not fit for purpose. In fairness to Casio, they refunded me without question. Shame, as it really did look a cool watch.

Took awhile but happy with end result
15 August 2023

For the final product, it would have been a 5* review, but there were a couple of issues.I originally went for the negative display model; for this watch, the negative display is counter-productive for this watch, especially with the compass, baro & alti. This watch has to have the positive display, which is what I exchanged the original purchase for. That watch is perfect.The Casio staff, as usual were excellent, and managed the return & delivery issues I had professionally.I highly recommend you review who you use for delivery, including the HUB collection points; they make your job harder & for a customer, buying an expensive watch, it is frustrating & reflects badly on Casio unjustifiably.1* off for the negative display & 1* off for delivery/collection ... MoreFor the final product, it would have been a 5* review, but there were a couple of issues.I originally went for the negative display model; for this watch, the negative display is counter-productive for this watch, especially with the compass, baro & alti.

UNREADABLE DISPLAY , RETURNED MINE
14 August 2023

SADLY , UNLESS YOU GO FOR THE POSITIVE DISPLAY OPTION, THE DISPLAY IS PRETTY MUCH UNREADABLE IN ANYTHING BUT THE BRIGHTEST OF SUNLIGHT AND THEN ONLY AT CERTAIN ANGLES.....NOTHING WRONG WITH THE WATCH OR FUNCTIONS BUT ONLY BUY THE POSITIVE DISPLAY ONE IF YOU WANT TO ACTUALLY USE IT !.......POOR DESIGN IMHO
