I have a Casio GW-300 "G-Shock" watch that has to be at least ten years old.  I rarely wear it.  It still functions, but for some reason, its display reads one hour ahead of the correct time.  I have set it for automatic Daylight Savings Time and for automatic synchronization with the atomic clock, and it's set to the correct city code. 


No matter what I've tried, the automatic synchronization sets it an hour ahead.  I have a PDF of the manual but haven't found anything in it that provides a clue to what's wrong.  I've gone through the process of manually re-setting but still, the next day it's an hour ahead.


Are there any G-Shock owners here who can help me get this watch set to the correct time?

I Love Mine

but it doesn't do that. They really are amazing watches; I own around 75 watches but this is my daily driver at home.

Can you lie to it about its location?  Like, for New York tell it it's in Gander Newfoundland.  For a more tropical motif, Bermuda.

Now, That's Smart-

Also--there are a bunch of G-Shock videos on YouTube. You might find help there.

Oh yeah --

I was thinking about fooling the clock by saying I was in Hawaii (but am not sure if Hawaii would use the LAX city code as well -- I'll have to check the instructions).  Hawaii is on Standard time all year, so it might be more stable that way. 


But then I was thinking, the clock is in Denver.  That's MST right now, which is one hour ahead of me.  I think maybe I'll just manually set to the right time and then shut off the automatic overnight calibration and switch to DST manually in March.  It's not like I don't have to do that already on all of the clocks around the house anyway.

I think I figured it out.

I'm pretty sure this was a case of misinterpreted symbols and semantics in the owner's guide.


I had DST set to "automatic" and presumed that the tiny "DST" display indicated exactly that.  Instead, I think it means it's set for DST, so that's why it's been an hour ahead.


As soon as the "DST" indicator disappeared, the correct time displayed. 


It's set to automatically synchronize with the Ft. Collins clock each night, so I'll be keeping an eye on things for the next couple of days.  If it maintains PST, then the real test will happen in late March.

I have an Oceanus that was made by Casio and absolutely love it. It has the same functions as the G shocks do but would have been a $500 watch that I got from a jewelry store that was closing. Oceanus watches aren't sold anymore, they are now called Edifice.

I like the look of the Edifice!


I only have the G-Shock because Dave wanted a new one and I took his old one.  I prefer watches with hands, though, but my other watches are more dressy, so the G-Shock is a good casual watch.

I got my first G Shock about 2005 for myself for Xmas. I used it till about 2013 when the display got a huge black spot in the middle and the battery would barely hold a charge. I bought myself the Stainless steel dressy analog/digital version about 2007 and it still holds a charge and works today. My Step Dad gave me his slightly newer G Shock after it went dead and he replaced it with the latest one. It turned out he never went outside enough to charge the battery and after sitting it in a sunny window it charged up again and has worked fine for me. You can buy new rechargeable watch battery for them for around 10 bucks, maybe a bit more if it is still good once it wont charge any more. The newest ones will pick up time signals world wide and have more functions. Mine truly have taken a beating and continue to work as long as the battery is good. I do chimney tuck pointing/repair and they get wet and covered with dirt and sand every day. The mineral glass display gets so scratched up and case worn down and they continue to work and stay waterproof.

One thing the Oceanus has over the Casio is a sapphire crystal. It's virtually unbreakable and aside from a diamond it won't scratch! A few years back Casio made a bad batch of batteries and mine happened to have one. I ordered a new one on ebay and swapped it myself and it has been fine ever since. I work nights and in the winter time I notice my power hand dropping down sometimes where I haven't seen daylight in a long time. But hanging it in the bathroom window for a day fixes that right up.

Me too!  Mine lives in the bathroom, just below the window in the never-used wall mounted cup and toothbrush holder above the sink.

The Edifice is a nice looking timepiece, as is the G-Shock. However both are too big for my taste. I prefer a smaller, slimmer wrist watch, one that doesn't get in the way at work or when wrenching on cars.


I found such with the titanium case Skagen chronograph. 41 mm dia, 9.25 mm thick. Full chrono. Nice infinitely adjustable mesh band (stainless). Mineral crystal that is very scratch resistant. It's very light and so comfortable I wear it 7x24 (not in shower) and barely know it's there.


I liked it so much when I found it, I bought a second one as a spare.



The only thing I wish it had, is a back light like some Timex watches have. However, I've had several Timex watches and the back light has failed in all of them. So.
