I got a wicked fast delivery from a Casio Authorized Dealer in Japan, on a JDM GW-B5600BC-1JF.

Casio just released this phone this month, IIRC.

features:
Bluetooth
Solar Power
6 Band Radio

This will update with the US WWVB "atomic" clock signal (Ft. Collins, CO) and 5 other locations
(Japan(2), China(1), UK(1) and Germany (1)) so if you're a world traveler, most of the populations in the Northern Hemisphere will be covered.

Should you be away out of range of those signals, or they're turned off, which might be a possibility for the US next year (2019)(lets hope not!)
you can use the Bluetooth feature to sync with your phone (Most phones (I want to say "all", but if I do, someone will prove me wrong) keep the same atomic clock
accuracy as they're updated from WWVB or more likely in sync with a GPSDO)

With Bluetooth, you can also more easily set alarms, and world time pre-sets a lot easier than pushing the buttons repeatedly on the watch.
You can even use the watch to find your phone! (as long as they're in range of each other)

To use the Bluetooth features, you'll need to install their app on your phone.

here it is, as I received it today, I'll have more pics later, as I ordered a 5 ring Nato strap and adapter for it, they should be here next week.



(box for everything, box for watch, warranty, tags, instruction, watch)

sorry for the crappy samsung phone pix

the 'yellow' is actually more like a gold mirror-ish. quite nice.

eta: I didn't buy from here, just a link to get more info if interested.

I got the strap adapter yesterday and will have the nato strap today. pics to follow later today

bit dusty. out walking the dog....

5 ring nato, that didn't fit with the nato strap adapter, due to it's size (taking up a lot of available real estate)
I clipped off one ring.    The rings are not as gold/bras as I thought they would be, they're really copper (colored).

thanks

you need to manually enable bluetooth on the watch to get it to connect to your phone,
so unless you do that, it's off.

the phone app will set the time, alarms and customize time zones.

the thing I don't like, is that the G Shock app keeps pestering me to turn on bluetooth.
it's not that bad, I just ignore it.  Oh, and another bs thing is the need to allow the app access
to your location. Why can't you just sync local time? or set it (local time zone) in the app?  I wish these a-hole
programmers would stop trying to "help me" by putting my personal/opsec information at risk.

every time I check the accuracy, it's dead nuts on.
I only live 70 miles from the WWVB transmitter, so I get a good signal and there is no need to connect
my phone for setting the time.
