Customers are mixed about the light of the watch. Some mention that the world time and auto light are really nice to have, the displays are shiny and catch the light, and the light is amply bright to tell the time in the dark. However, others say that the digital displays are impossible in low lighting or in the darkness, the face backlight isn't that great, and that the backlight only lights up the dial, not the LCD.

"...Perhaps the night light could be a little better to also let you see the LCD screens, but this is not a big deal for me...." Read more

Customers are mixed about the readability of the watch. Some mention that the dials are very easy to read, the small windows are very clear, and the hands are bright and easy to see. However, others say that the displays are hard to read with the LED light, the red hour hand is difficult to read at a quick glance, and that the color hands look cool but hurt readability in low light.

Amazing analog g shock with just 1 problem
4 Stars
Amazing analog g shock with just 1 problem
I love that this watch has multiband 6 and is solar powered. I have not had any issues with it syncing every night. The hour hand being red makes it really easy to tell the time at a glance. The watch does have lume on the hour and minute hand as well as all of the hour markers. The lume is not too bright but if your eyes are adjusted to the darkness you will be able to read it at night.My only complaint is that the light is orange and I like that because if you do need the light to tell what time it is at night it does not blind you. But the main issue is that the subdials are not illuminated by the light. I have set a timer and have not been able to see how much time I have left without turning on a light or using my phone to shine a light on the watch, which at that point I might as well use my phone for the timer. Also another minor gripe is the lume on the minute hand is all the way at the end and it is almost the same size as the hour markers. At night I can tell the hours easily but some times I need to tilt my wrist to see where the minute hand is if it is on one of the hours at that time. I say minor gripe because you can use the light to see where the minute hand is easily because of it being white it shows very easily when the light is activated.Overall my favorite analog g shock yet. I just wish the subdials where lit by the light in the watch and it would be a 5 star rating.

5.0 out of 5 stars My new favorite
Reviewed in the United States on July 28, 2021
Had this watch for around a month now. This watch is amazing for the price. I love the style of the dial. It has a honeycomb pattern while also having a sunburst effect to it. The applied indices, gshock logo, and rings around the digital displays are shiny and catch the light. The red hour hand is a nice, small touch that adds a bit of style. Also like the stainless brushed bezel. Its brushed on top, and polished at the edges. I really love looking at this watch a lot. Its a watch that I look at often, even when not looking at the time.

The size is perfect for me and my 6.75” wrist. Its not bulky, but has enough meat to look manly. I don’t think its small, nor large, but a goldilocks size. It has solar charging and atomic clock reception. A real get up and go watch compared to my automatic watches.

A lot of people complain about the red hour hand, but I have no problem seeing it in dim light. Nor do I have a problem with the led light. It lights up the dial enough to see the time. At night, I really don’t have a use for the digital displays, just the time, so its ‘enough’.

I initially had problems getting the atomic clock sync. But found that the watch has a hard time getting reception if its laying on its side. If I afix the band as shown in the picture, so its standing up, it picks up the signal almost every time at night.

Like this watch so much, I might pick up the blacked out version. Everyone is going crazy over the GA2100 gshock, but I think this watch offers so much more at the same size, weight, and price. This watch also has more features and better quality (the ga2100 is all plastic dial), IMO.
