Review GW300B-1A G-Shock
I want to get right to the things that stand out the most,
before I forget them...

The quality and accuracy of the way the minute, hour and
second hands align with the demarcations is really stellar. I
have other Casios where this is not the case. This G points
directly at the lines, all hands, even under magnification.
Even the tiny complications are perfect. If it's off anywhere
around the dial, it would be such a slight, ridiculously small
amount as to be of no concern. Casio did a fine job of QC with
this watch.

I just read a little of Cal .45's review of his "near perfect G" and I had
to chuckle when his positives include "black, with no color
highlights... like orange..." Personally I am blown away by the beautiful
orange/black theme of this watch. It's the main reason I bought it. (eBay,
$197 + 8 shipping) Orange seems to be very me lately. Last year I picked up a Repsol Honda
motorcycle, and right now I'm training in TX
for a product that uses orange in their logo. The watch is
right at home in their offices.

It is incredibly easy to read - the contrast between hands and
dial is great. You'd think that the orange numbers are not
Lumibrite - but they are! The plainly visible glow paint on
the hands is brighter than the hidden glow paint on the dial,
but the hands and numbers all glow. (Not the second hand.) I
love that it has a second hand, by the way. I really miss that
on the G-1250BD-1A

It's very comfortable. As usual, the G-Shock resin band is
very supple. I have a lot of steel bracelet watches, and
though I favor metal, it's fine this one is resin.
It's not that heavy - I'll shoot off a measurement when I take

You cannot turn off the MultiBand-6 reception. I guess I'll
have to place it in an EZ PASS foil pouch at night if I want
to keep it set fast.

The four buttons to set it are similar to other G's, but not
the same. There was a learning curve for me with this one, as
opposed to the ProTrek PRG510T and G-1250BD-1A, which are so
very similar to operate.

The depth and layers of relief on the face are stunning - totally cockpit.
It has an alarm but no hourly chime, and no dial light.

A little weirdness...
The world time (London) is off by 1 hour, meaning it's behind
an hour, even though I correctly set it for DST (which
corresponds to British Summer Time) and my home city and DST
settings are correct. It's 8:15 US central time, which is a 6
hour difference between here and England. According to time
and date dot com it's quarter after 2 in the am over in London
town. This G-Shock shows quarter after 1. I have a lot of G-
Shocks and I have made the DST mistake when I was a newbie.
I'm not making that mistake now. I don't know what gives.

The site is having issues with attachments now - but you all know what it is.

Review GW3000B-1A G-Shock

A little weirdness...
The world time (London) is off by 1 hour, meaning it's behind
an hour, even though I correctly set it for DST (which
corresponds to British Summer Time) and my home city and DST
settings are correct... I don't know what gives.

Apologies for mis-typing the model of the watch in the orig. post subject line. I was on a laptop without the pwr supply, and as soon as I posted it shut down. Too much of a hurry.

The problem with the World Time City was me, of course. I was reading the 24 hour WTC display incorrectly. The marked numbers 6,12,18,24, with the thick and thin lines between them, fooled me at first glance. Between each of the stenciled integers there are six hours of time, so each thick line indicates 2 hours. I wasn't using the context of the nearest numbers, and was mistaking each thick line for 1 hour. The attached pictures show the correct London time as just after 2pm for an indicated 9:08am EDT here on the east cost US, GMT-5. Parallax is deceiving in the pic, but that's it.

The WTC "right hand dial", as Casio calls it, bagged me. I guess it's worth noting that this is not the best watch for world time. My G-1250 is so much easier to read for that.

This is a great watch and I highly recommend it. Even without a dial light, steel bracelet or hourly chime, maybe my favorite of all my G's. I just dig the orange-on-black so much. (Happy Halloween)

  • It weighs in at 2.72 oz, or just over 77 grams. Very comfortable indeed.
  • Stopwatch limited to 24 mins elapsed time.
  • No timer mode.
  • Large easy to see date
  • No way to disable MultiBand 6
  • Not sure about the crystal - I'd guess it's mineral, but not sapphire.

Its large 32mm face is carefully laid out to provide the look of an aircraft instrument panel and is constructed of two layers creating a dramatic 3-D effect for the sub-dials.

Large metal side buttons provide easy operation, but at the same time, are enclosed by guards that protect against accidental operation and damage.

For added durability, its band is fastened on both sides with stainless steel screws for plenty of durability.

Please see attachment. This method definitely works.

"It's in the bag", you might say.

From midnight to 6 am.

You actually CAN disable the Multi Band 6 feature. After I re-read the manual a couple of times, I noticed that it says something like "the multiband 6 receive function does not work when the watch is in another mode". So I'm pretty sure that if I choose the stopwatch mode, and just leave it like that overnight, it fails to receive the signal. So that would be one single press of the lower left button (C, on this watch) and the waveceptor feature is disabled. Believe it or not, it actually picked up that freaking signal inside this aluminized bag!! Holy cow. So the method above is not the be-all end-all. But since I have been leaving it on stopwatch, it always registers N (no) in the morning, when I check the state of the last received signal. Of course I know that just by looking at the time.
