Thank you! So many tutorials with Indian accents that I can’t understand. Finally yours is the best👍

[@Konstantinos143]

I hadn't bought a watch like this for more than 12 years. I am trying to live without my cellphone and so a watch to tell the time was the reasonable step. Just one problem. I couldn't turn the light on. Once I saw in the vid how you did it, I was laughing so hard at myself! Thank you, awesome devices indeed!

[@WatchGeek]

Thanks!! Make sure to subscribe and get in on the giveaway, as there are a few days left for a chance to win a Gshock

[@209FlyBoy]

I bought one today and all the ones i didnt like had the light. So i bought one i liked thinking it didnt have light. Got home and almost dropped it so i grasped it hard and the light was on😂 turns out the little black part isnt for looks. Its the light😂

[@alunwidjaja6498]

Just bought a gshock watch 900adr series and i was shock cos i didnt know how to adjust the time. Reading the manual actually make it more confusing. Thankfully i watch your tutorial and found out that it has a lot function and actually convenient once u get use to it.

[@kostantinosaspiotis798]

Thank you sir for helping me get out of my misery. Spent like an hour trying to figure out how to adjust tz time date etc. After watching this the job was done in like seconds. Magnificent video that got u a new subscriber. Greetings from greece!

[@pavithranath6609]

Thanks for your tutorial. I purchased this watch 1 year back and upto now I don't know that this watch has light. When I have asked the store keeper about the light option they replied that this watch does not have the option of Light, but after watching your tutorial I tried for the light option and its working fine. Once again Thank You Very Much for the tutorial👍

I tried holding the light bar down for about 5 sec's and nothing happened also 'Watch Geek' never mentioned this (battery wasting) function, so the answer is no I'm afraid.

[@primoyliaster4148]

Anubody know the Casio fishing gear WS-1200H digital watch? I loved it, the fishes on the upper screen. One thing that i do not like is the LED light. & i wish for Casio to make the very same model with a blue-green electro lunimesence backlight, which i like, instead of LED, which i hate LED light on digiwatches. Anybody agree? Please share my proposal all over the web, until it gets the attention of Casio. Thank you very much.

Hi WG, my wife is threatening to divorce me if I buy any more G shocks because I read your reviews.Seriously, are the alarms and beeps audible on this watch, as they're normally useless? Many thanks. Terry Davis

[@terrydavis1488]

Thank you. But how about the alarms?

[@WatchGeek]

They are not able to wake me up, so no, they are not as loud, usually solar models are quieter than regular battery ones

[@phucha8512]

Thanks for video but Sick of it. Never buy again

[@tmarq4655]

One thing for sure, the instruction for using this watch are probably the worst written in the world. The technology configuration must have been done with 6 different nations, the button setup sucks and programming suck, the design sucks, over all, I give it a -2. Thank God I own several rugged watches that are far less of a hassle to use. I will be selling mines offf and will never buy this piece of crap again. Oh yeah, even the manual sucks, too.
