No sé si ya estaba inventado, pero ahí está, el futuro se acerca. Cesium-based oscilator wristwatch, casi na'. Un desvío aproximado de un segundo a los 1000 años.
Ahora, feo es con ganas. Supongo que una caja tan grande y aparatosa será necesaria para el mecanismo. Supongo que con el tiempo se irán reduciendo tamaños y mejorando diseños.
No es precisamente esto a lo que estaban acostumbrados a hacer en Bathys Hawaii http://www.bathyswatch.com/main.php
Este es el correo que me ha llegado:
I'm feeling over the moon today as we have achieved something we set out to do months ago: create a genuine cesium-based atomic oscillator wristwatch. This is the real deal folks! And no, we didn't invent the chip that underlies this watch - that was done by a pair of award-winning physicists at Sandia National Labs in Los Alamos. But about a year ago I heard of this technology and thought, "Let's make a watch built around this chip scale atomic clock". And tah-dah! Last night we got everything off the bench and squeezed into a self-contained, self-powered wristwatch. We are the very first group to do this! Much thanks to George Talbot, a very talented engineer who did a lot of the tricky integration work.
If you believe in divine intervention (or not), consider this: after getting to a point where I needed help doing the electronics side and finding literally no one here on Kauai - I went where I always go when I need something: Craigslist.
First ad I called was George's...did he know anything about timing and electronics? Well turns out George already had LOTS of experience with cesium-based frequency generators and atomic clocks. He had even already worked with the chip we were using. And he lives on Kauai and would be happy to help. What are the odds of this I ask you?

So yes, it's currently a huge watch. It's "inelegant" as I like to say.
But that will change soon.
We wanted to get this prototype up and running as a proof-of-concept and be the first company to use this technology in a wristwatch. We see many interesting applications of this tech - for example combined with the TX/RX RFID technology we developed in 2009, it could be possible to timestamp remote receivers to track users locations in a GPS-independent manner. The chip has untapped potential that we might exploit in future versions.
We've got another iteration already underway that includes a thinner, lighter carbon fiber case, LED status lights (this watch has to attain "LOCK" - is that cool or what?), a COM port that lets the owner monitor the status of the internal laser, the cesium gas heater, the contrast of the hyperfine cesium lines - even to "train" the watch to be even more accurate. Already this first version is rechargeable and runs on LiPo batteries mounted in the case.
I think most folks would have done this watch as a digital timepiece, but I like the idea of modifying a standard analog RONDA moonphase movement to display the time. We also designed it to keep running even if one needs to adjust timezone or the date.
One thing I like about the Cesium 133 is the philosophical aspect.
I mean, why make this watch at all? (We got asked that repeatedly as we were doing this). Nowadays, accurate time is as close as your cell phone. Of course, then again, why wear a watch at all?
The Cesium 133 pushes at the boundaries of what can be done: more like flying around the world in a balloon than building a better mousetrap. We relish stuff like that. So that's why we did it.
Please feel free to share this news on Facebook, on forums, in the media, etc.
Spread the stoke!
All the best from rainy Kauai,
