Citizen Satellite Eco-Drive Watch: Gets Time From Space

Citizen Satellite Eco Drive Watch: Gets Time From Space   watch releases

Atomic clock radio signal syncing watches are so last year. Citizen just decimated the coolness factor of those watches with the Satellite Eco-Drive watch. This timepiece isn't just a concept, but will actually be produced as a limited edition later this year - and may have its tech show up in later watches. In a nutshell, the watch keeps its time super accurate from syncing with the navigational satellites that orbit Earth as opposed to syncing with radio signals that are broadcasted from local atomic clocks.

Atomic clocks lose one second of time every 100,000 years or something like that. Maybe even longer. The point is that you'll be long dead before they are off by even a fraction of a second. Your standard quartz watch movement is accurate to within about 15 seconds a month. Syncing to an atomic clock is a good idea, and has traditionally been done in watches that do this by relying on radio signals that atomic clocks emit. However, there aren't atomic clocks all over the world, and neither are there such signals. If you live in the US, much of Europe, China, and Japan you can get atomic clock radio signals, everywhere else you are screwed. Even if you are in-range, the system to capture the signal and sync with it is quirky at best. I have a few atomic clock radio signal syncing clocks and am really never sure if they are getting signal or not. Navigational satellites that orbit the Earth, do however, get the signal.

What Citizen has done with the new Satellite Eco-Drive watch is create a system that receives signals not from radio towers but from the satellites. The main advantage here is that now your watch can be hyper accurate anywhere on the planet - not just regions where the radio signals are present. The watch also has an Eco-Drive quartz movement that receives power from the sun. Your "stranded on a deserted island" choice of watch just got upgraded.

The only drawback is that the watch cannot receive a signal indoors. Think of it like a GPS unit. To receive a signal from the satellite it needs a clear line of site. The watch can receive information from one of 24 navigational satellites the are going around the earth. These satellites bounce the atomic clock information to each other so that are each all accurate. In addition to the time, the signal also has the calendar information. What amazes me the most is that the watch has enough power to do all this.

Citizen gave the watch a spacey conceptual look to go with the Satellite theme. The dial is open and is mixed with black, white, and green colors. The flange ring is a green coil, and Citizen admits that the design is meant to make people think of satellites and spaceship engines. Not stopping there Citizen went so far as to partner with makers of the upcoming Appleseed movie sequel "Appleseed 13." It is actually the third move in the franchise... The watch in animated form will be in the movie.

Not sure about the case size, but it is nice and large. The case will be in steel and ceramic (very cool). The crystal is also sapphire while the case is water resistant to 100 meters. Inside the watch is a Citizen Eco-Drive calibre H990 quartz movement that offers the time, satellite syncing all over the world, a perpetual calendar, second timezone, and world time. The watch will be limited and in the $3,000 price range I believe. Finals specs on price and production amounts will come later when the watch is due for release in the Fall of 2011. Very cool and I love to see the revolutionary technology from Citizen.

The design of this watch is looking absolutely brilliant. I am very much impressed with its design. I wish to have the same watch like this.

Citizen is really collection of fantastic watches, each model has it's own specialty.

I have a Satellite Wave for sale!!

It is 197/990 will be posting soon.

If someone is interested let me know

Hallo Watch-friends!

In 8/2009 I wrote my letter to the Pres. of Citizen, Mr. Tsuneo Nagai. Wrote that "Is time for GPS-Time"... Got a short letter back with thanks for my idea. Two year later it is done, the concept of accurate time all over the world. Im Proud of ... Citizen. The idea came to me 2008 in Namibia, got my old Garmin-GPS with me to correct my Citizen Pilot H461. Now lets celebrate! (As a medicine-Doctor I had no time and interest to make patents...)
Thanks to the President and the stuff of Citizen - Well done!

I am really excited about this watch and honestly wonder if this watch could be considered both an fantastic timepiece and a piece of horological history?

Also, an possible caveat that comes to mind: what happens 30-years from now when satellites are either replaced by newer satellite models and/or the software inside the timepiece used to read the satellite telemetry is obsolete?

I would appreciate your take.

I called this forever ago - someone owes me lunch, I just need to remember who.
It's crazy cool, in all the little details - like the hour hand thast comes from inside the watch and is bent at a right angle.

Interesting concept, although I wonder - GPS itself isn't an alien concept to watches - especially the running computer watches made by Polar, Timex, etc. all have GPS in them. I wonder why none of them ever thought of making their watches sync up to GPS for time?

To be fair most of those Polar/Timex/etc. watches are not really fashionable or something you'd really want to wear all day, so the time accuracy probably wouldn't be a big selling point.

But either way, interesting that Citizen seems to be the first to take advantage of this concept. I kind of wonder why they didn't factor in some other GPS functions too though - nothing complex, but showing lat/long, maybe a function where you could set a marker at a geographic location and then have it be able to point the direction to it later on when you ask.

This is a gorgeous watch. Its too bad it will be impossible to get in North America.

I just watched the video, & continue to find Japanimation (new word?) alive & thriving for many venues. It was ahead of time in the 1960's, today it continues to forge into infinite voids.

After this, Citizen can market their watches that run/snyc on interstellar/galactic waves.
Do aliens suffer from intergalactose intolerance? (LMFAO)

Wow!
Just watched the video; the watch is even more seksi there, I do NOTthink the photos do her justice, whatsoever.
That manga film is going to drive the demand for this first edition thru the ceiling; there's going to incredible demand; overseas; guessing from the sapphire crystal, and I'll take bets now of a good 150-200% mark-up on these come September. If you can even get one, I'm off to my fav, AD this morning to try to get an order in, and to put them on notice to bring two in for me.

As to whatever time delays that may be there, GPS time works good enough for the World's militaries [and commercial airlines and ships at sea] so as to target WMD's with pinpoint accuracy; so, it's good enough for you mate.

Too Kool for School.
Guess it's time to upgrade my 3rd gen Skyhawk AT.
Citizen is my fav watch co. of the past decade [except '07 where Accutron ruled the year with their "VX" series].
They've had a rash of mega-hits over that time.
Citizen technology; borders on magic.
[if they start using that as a slogan I wan't a cut]
[I'm betting that the green coil is an antenna]
[Switch that green to 'Skyhawk orange' and... .]

Have to say i am blown away by this watch the concept and design are off the wall ,a great selling point for tech nuts .I would buy this just to say i have it.

Interesting concept, a bit cheesy on the design of the watch and the promotion.

I wonder how citizen gets past the physics limitation, if they bother to do so at all. Namely the speed of light. If the GPS satellites are syncing to the atomic clocks on the ground, there has to be a millisecond delay as the radio signal travels from Boulder to a satellite 23,000 miles above the earth (GPS is in Geosynchronous orbit, essentially each satellite rotates the earth at the same speed as the earth).

Then there's another delay as the satellite's signal is sent back to earth. Again, 23,000 miles back down, another millisecond or so. Light and radio waves travel at 186,000 miles per second, so it's not much of delay, but still.

The watch is then syncing itself to the satellite's clock as it was a millisecond or so ago.

It would seem that the standard atomic radio watches would offer greater accuracy since those signals (which I can tune into right now on my shortwave receiver) are purely terrestrial in origin and only need to travel a few thousand miles from the radio tower.

Very impressive but on a deserted island a 1j Mickey Mouse Timex would more than suffice.

The Timex watches (and I believe the Garmin units) will sync up to GPS time.

Good luck with the order having watched the vid the best way you'll get one of these is with a gun

Also, i'm sure they knew this and so made the calculation of time that little bit fast, deliberatly, to get time perfect.

Dean Grant Baker
Dean Grant Baker

Nowhere near milliseconds; try nano seconds; further as long as the delay is LESS that a half second then everything is fine; as you see, the watch is only capable of timing to the nearest second, so if the delay is less than 0.50 seconds then accuracy will be perfect to said nearest second.
So your point is moot; as is your understanding of how "AT" watches work.
