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 battery has given up the ghost, and it's probably in a box of stuff around here. At the time, putting a new rechargable in it was impossible. I wonder if that's changed now... Edit: Neglected to mention mine was also solar

Maybe keeping it charged is key. I have had mine for almost 10 years.

Had the GW9400. Now using GWG2000

Works flawless in Seoul and Beijing. A month in South Bay and flawless too.

There is no signal for this back home in Singapore. What I do - since we also don't know when they're gonna shut off the radio towers - is use an app on my Tab S8 Ultra, set my watch's time zone to Tokyo, leave watch right next to speaker and go do something else. After some beeps and minutes : my watch time is readjusted.

No fiddling.

Mine stopped holding a charge somewhere around the time you got yours. I recall picking it up at the PX in the summer of 2003...

However, I will dig it out and see if it can be resurrected.

I guess, but still, these seemingly large numbers are still a minute percentage (e.g. probably 0.00001%) of overall costs/revenue that are relatively way, way more. I would understand manufacturing pain, and the ROI just doesn't justify it. But saying that it's solely to do with costs doesn't line up, IMO.

For auto industry, that's big money. VW creates small inserts and adds them to their motor covers for Seat and Skoda. If you pry that logo, there's a molded VW logo on that plastic engine noise cover. Stellantis shares tons of parts and software. Peugeot 2008 and Opel Mokka is essentially the same car. They share the same shifter, electronics and software stack sans the skin applied to displays and LCD geometry. Even…

> Key fobs are even funnier

On Aston Martin key fobs, when the rubber coating wore off, it literally had the Volvo logo underneath. Ford parts bin.

I'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.

GPS signals are much higher frequency and very low power and thus don’t work indoors. These HF time signals are way more powerful and can be detected inside buildings.

In the interest of the previous reply, Casio's GBD-H1000 has the ability to time sync with GPS.

I inherited one of these Casio Waveceptor watches from my father. It routinely will set itself to a totally random time far into the past/future. I've wondered if maybe contemporary wireless devices interfere with the time sync radio. Another possible factor is the watch itself is ~20 years old.

I've used a series of them for over 20 years and never had this issue.

Why you think manufacturers went into touch surfaces in cars much to dissatisfaction (that eventually caused some to back up) of customers? Every button needs a bit of plastic moulded, a (good quality) button, backlight, often LED to signal whether it is on or off, and whole control block needs microcontroller to pack it into CAN bus and CAN bus connector to send. Make whole thing a touch surface and you're saving bu…

Strictly speaking a touch screen is massively more complicated than a set of buttons. you now have billions of gates that have to be produced at nanometer scales in some of the most expensive factories on earth. The price to develop and manufacture a touch screen is many times that of a set of buttons. The fact that it is a generic interface drives the cost per unit down quite a bit. it does not hurt that the incredible manufacturing tolerances that must be maintained almost force the automation of the process allowing costs to be even lower.

I just wish we ended up with aircraft style MFD's instead of touch screens. You know those things with a screen and a row of buttons along each side.

Yes, 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…

My dad has a g-shock that lasted 15 years. He loves it. Model: MTG-M900DA-8CR. I bought him a new one a month ago, snd he almost cried because he was looking for this watch in garage sales. He asked me to set it, we looked and both watches were already set to the correct time down to the second. The face has a solar panel that you can’t see.

Have you...used them ? My Protrek basically doesn't sync if I'm at home, and as it tries to start sync after midnight the auto sync near-never works. I installed DCF77-emulator app on phone to get around it. My radio-synced clock works fine but comes with big (BIC lighter size but double the thickness) external antenna. Probably much worse in microwave that's somewhere inside the house and not near window > All you h…

My dad loves his. I bought a new one for him after 15 years of use. Both watches were the correct time. He swims a lot in it, and the old one is much smoother than the new one. I love that guy.

There is already a time signal in the electrical grid: https://www.meinbergglobal.com/english/info/time-synchroniza... > Why don't they just always use this Tech. I don't understand. The bit's that get your oven to work don't need the time. Adding the bits for this is a cost and a thing that can fail because it can't receive the radio signal that equals a Dead on Arrival for your oven and a service call at least. Whe…

As mentioned by a parallel commenter, your link doesnt say what you think it does.

That said, the most power line synchronization is useful for is clocking not time, and to be very honest, its only a consistent clocking source in some places (who perform adjustment to ensure a long term value of 50/60 Hz), which means it can be used to provide a clock source to keep a device in sync, which already knows the time, but cant be used for cold start of a device.
