The GA-100-1A2, just like the others in the GA-100 series, is a Military Series G-Shock and can withstand rough conditions and terrains. Like all casio G-Shocks this is Shock Resistant up to 100m as well as being 200m water resistant. The GA-100s come with a bouns though and are magnetic resistant as well, so if you need to synchronise your watches, this will do the job.
With a large case it's easy to read and is also Analogue-Digital with blue analogue hands*. The light up feature present on most G-shocks will light up the analogue hands only, saving you any issues if you're sneaking around, or if you want to check the time without waking up your partner.

one year later review by Eddie N on 23/07/2017
Came back to get another watch and leaving review for my last one. After hearing so many nightmarish things about purchasing watches online, I tried this site, and the watch is perfect! Big enough to fit on my wrist, not too oversized, and as I said it's been a year and I haven't experienced a single problem with it!
Second G Shock review by Mack K on 16/07/2017
I had one 12 years ago and it just died. Loved my old G Shock so bought this.

Sweet looking review by Aiden J on 5/06/2017
Great watch, loving the mix of colours. KINDA hard too see the digital but i'll get used to it
So far so good review by Jimmy W on 8/05/2017
It's a little larger than I hoped but still pretty good. I can see the digital display but only if i angle it just right so that's a bit of a pain.
G-Shocks are the best review by Jezza L on 1/05/2017
I honestly don't know why people get anything but G-Shocks. Fantastic price, great durability, love it.

Fun watch review by Josh P on 9/02/2017
Bought this because I needed a tough watch. I like all the cool features, particularly the 5 alarms as it helps with my meds. Only down side is the digital screen seems a bit smaller than I thought.
Great watch with lots of cool features review by Lou G on 8/02/2017
Great watch during the day. Easy to see the time whether I look at the analogue part or the digital. Also like that it's magnetic resistant, since I work with magnets every day.
A good watch for my boyfriend review by Penny S on 2/02/2017
What a find!! Wasn't sure what to get my bf for Christmas but he loves this! He has a massive wrist and it fits perfectly. And the price was great!!
Great experience! review by Kev J on 1/02/2017
Bought this for New Year's and got it a day after I ordered. I had told them it was a present and was really surprised to note they put a "fragile" label on it to make sure it would arrive undamaged. Thank you for the thoughtfulness!
Stylish review by John D on 16/09/2016
The black and blue really mesh well together! Looks great on my wrist.
Military approved review by David on 1/09/2016
Got this for my brother, he's in the military and his other watch couldn't withstand basic training. It's really helpful that the light only shines brightly enough to light up the analog. Means it won't break his cover at nights.
