Re: Casio G-Shock time sync radio
#72I wore a G-Shock Wavecepter while serving in the U.S. Marine Corps. I recall that on both of my shipboard deployments (2004 and 2006) I was very excited to have my watch set time automatically. It indicated that I was finally nearing the U.S. East Coast. It helped to be an aircraft mechanic on night crew, as I was usually on the flight deck when it tried to set time.

There is a plot device for a Tom Clancy novel in this little factoid.

Oceanus S100 is absolutely brilliant. Solar powered, radio time sync, titanium (so incredibly lightweight), waterproof, and looks like a dress watch. The only downside is they are only sold in Japan so you have to import them.
42mm is huge though
It really doesn't feel large, I think because it's so slim (it's quartz) and light.

Have solar atomic version. Don't wear it much these days. Mostly when I travel. Been on my dresser 2 years collecting dust but gets some sun. Picked it up the other day for a camping trip. It was both charged and had the correct date and time.

My professor is a materials/mechanical engineer and in contact with many auto companies. He told me of the following dialogue: Prof: Why did you stopped adding passenger side handles? How much one cost? CarGuy: Around €1.50 Prof: That's not much? CarGuy: A new car leaves the factory every 60 seconds. Prof: Oh. For the lazy, that's €2,160/Day, €64,800/Month, €777,600/year.
€777,600/year seems negligible for the industry.

Re: Casio G-Shock time sync radio
#76Yes, as others have stated this is an old technology. I don't really understand why this is not more common in the modern day. it's not really that expensive to implement and they did it with analog chips back in the day... Why do we have to set the time on our clock radios or on our microwaves or whatever? Why don't they just always use this Tech. I don't understand. All you have to do is allow people to store an of…
It does feel like something that’s easy to cut from a bill of materials though, nothing else in the microwave relies on the time being accurate. Probably not expensive to implement, but if you’re building a lot of them, I imagine the ~4cents per unit (maybe more, just guessing) adds up fast.
I would gladly pay 4 cents more just to never have to figure out how to set the time on my oven or microwave ever again.

#77I have Casio GW-M5600. It's a perfect watch.
- Looks like classic G-Shock.
- shows correct time always (time sync)
- never runs out of battery (solar charging).

And daylight savings?
Radio syncing is perfect for forgetting about setting clocks for DST on/off because the sync automatically does that for you.
Reminds me of the clock I bought which changed MST/MDT automatically, which forced me to adjust it twice a year unlike like all my other clocks, because I lived in Arizona.

There's a Lineage LCW-M100TSE that should be a bit cheaper - titanium, sapphire crystal, radio sync. Also JDM though.
I have this watch and I love it. It's incredibly light due to titanium case and strap, and very tough with sapphire glass. Solar powered, so never needs the battery changing, and always accurate due to the radio receiver. And I like that it looks good without being pretentious, or a display of wealth. It's just a Casio, but those who know, know.
Re: Casio G-Shock time sync radio
#80I'm curious why we don't just use GPS's UTC time broadcast to set time? I understand that using GPS to track satellites and find location is power hungry, but I can't imagine that simply receiving a time and setting a clock is any more power hungry than this system.
