Great watch from looks and accessibility. Although, the backlighting was not to expectations. When backlight comes on you can only see the hour hands, the digital aspect of the watch is hardly seeable. which is a disapointment due to the quality of the photos you would expect the same when seeing watch in person.

This G-Shock watch represents good value. The functions in it are all that one requires 99% of the time. It is both functional and can take some hard lifestyles. All black version is stealthy and the coloured options look cool. The included setup manual is very basic, but there is excellent help online for this model. I can fully recommend this G-Shock watch and I dont think you will be disappointed.

Blue Bezel Watch GA100-1A2

I am happy with this purchase. I read some reviews prior and can add that thje backlighting serves no purpose and the watch is hard to read in low light situations. This is not an issue for me but the design prior to release should resolve these issues. as they add an negative undertone to what is a good product. For me I would give it 5 stars of not for the readability issue.

Daylight biased reversed feature windows.
26 July 2021

The yellow is pretty much the yellow of Lego. It matches my Jeep. Corvette, Porsche and Ferrari use a similar color. Ford's yellow is a tad more orange. It's dandelion yellow, not banana. I don't get the reviews complaining of a misleading color. It's spot on in the pictures. The watch itself is cool. The speed hand at 12 o'clock is of dubious value but maybe I'm not timing many aircraft, IDK. The reversed information windows are great in the bright sun but of little value in normal inside light. Still, this watch is more style than practical unless you have a specific application. The lighted dial feature will show the time and is pretty nice in total darkness but you won't get anything other than the analog time and a cool looking face with the light feature.

Fake or original not sure from this seller

The watch looks good and has all the functionality required..ButI didnt not receive the warranty card for my GShock watch and no tag on the wat ch..Which is making me think about the originality of the product it self .I also didn't receive the product manual in the box.

Gshock Ga100-1a1 is awesome!!!!
25 February 2020

This gshock is one of the toughest,best looking watches iv ever owned. It is a X-Large cased watch which makes it that much more better, and the black on black just really makes this watch pop . Now one thing people do not realize about these military blackout version is that the LED back light is not going to be a super illuminated that's going to light up a room. This watch has an amber led that gives you literally just enough light to see the analog hands of the watch. Which it is less distracting but then again it would be nice to see the face of the watch. Iv seen both good and bad reviews for this watch well before I ever purchased it but as for me I absolutely love it. It wears comfortably its suits good on a 7and a half inch wrist and it's not as heavy as it ... MoreThis gshock is one of the toughest,best looking watches iv ever owned.

All in all I would recommend this Gshock to anyone wanting a tough,great looking everyday watch that will stand the test you put it thru and then some. I own several gshocks, 18 total from this blackout Ga100 to the frog man to each version of the mudmaster and unless its something absolutely formal I chose this ga100 every time. You will not be disappointed buying this watch. But do your research and make sure you are buying from a authorized Gshock dealer because there are plenty of scammers making copies. Believe me it's worth the extra money to have a true authentic Gshock.

I have recently started watching Sky's entire series of Strike Back the story of the deniable ops section 20 and their fight against various nasty terrorists while my wife watches Love Island in the bath.I have become obsessed with Damien Scott one of the ex special ops heroes who swears more than a dozen carpenters simultaneously hitting their thumbs with a dozen hammers while shooting nasty really badly trained baddies who couldn't hit a barn door with a banjo.I dipped a toe in to my obsession by purchasing a para cord bracelet..I mean arm band as worn by Scott and it really did make me feel part of the team.After discussion with my wife and actually watching the final of Love Island to seal the deal I put it to her that obviously I couldn't justify spending ... MoreI have recently started watching Sky's entire series of Strike Back the story of the deniable ops section 20 and their fight against various nasty terrorists while my wife watches Love Island in the bath.I have become obsessed with Damien Scott one of the ex special ops heroes who swears more than a dozen carpenters simultaneously hitting their thumbs with a dozen hammers while shooting nasty really badly trained baddies who couldn't hit a barn door with a banjo.I dipped a toe in to my obsession by purchasing a para cord bracelet..I mean arm band as worn by Scott and it really did make me feel part of the team.After discussion with my wife and actually watching the final of Love Island to seal the deal I put it to her that obviously I couldn't justify spending £500 plus (probably) on a sub machine gun like Scott's, however, an essential part of the kit worn by Scott and his partner Stonebridge is the Casio G shock.There are numerous discussion forums about Strike Back and one about which G shock!Turns out he wears different ones but I liked the look of the G100 1a1er. My little very wife agreed that I should get one ( to shut me up no doubt) and it arrived yesterday. It is brilliant the manual was a little tricky to follow until I realised timekeeping mode is the mode that shows the time and date and then I was away. I'm looking forward to using the countdown mode so I can revisit the episode where Scott and Stonebridge had to simultaneously defuse 2 nukes in different locations/ time a boiled egg.I am struggling with wearing the watch with the face on the inside of my arm like Scott so that I can glance at it while firing a sub machine gun but until I approach my wife about the sub machine gun purchase I will wear it on the outside like normal people.Love the watch love strike back.I'm 51 years old is this normal?
