Atomic watch, would you?
Discussion
The design might be a little funny and it does appear to be quite big, but who wouldn't want an atomic wrist watch. Accurate to far better than anyone could ever possibly come up with a good reason for, and available now at $6k.
I hope it's waterproof as it probably runs at quite high voltage, and cesium reacts very violently with water!
Just googled the Cesium chip, and available for about £1k if you want to build your own.

Who now own Broadcomm, LSI and PLX. I wouldn't be so dismissive of a company selling 1 processor into every smart phone.[ETA] Avago, forgot to add that they also have Avago. Well technically, Avago have LSI & PLX. Broadcom have Avago and Microsemi have Broadcom.[/ETA]
Damned if I'd want one though. Quartz watches are too accurate for my tastes.

Still, for bar room bragging rights it's up there with a mercedes sls.
Took me a while to find a thread for this!
The limited edition URWERK AMC is a hybrid timekeeping construction that consists of two autonomous, but linked, systems. The first part – the Atomolith - is a fixed base unit, a 35kg aluminium-housed atomic clock a bit bigger than a briefcase. The second part is a mobile unit, a purely mechanical watch that can be worn on the wrist or securely docked within the base unit. When worn, the accuracy of the mobile unit is dictated by its 4Hz (28,800vph) mechanical oscillator and the conditions it is subjected to. When docked, the mobile unit is synchronised with its base unit, via a complex and ingenious system that senses any timing discrepancy between the two and chronometrically aligns the mechanical movement of the wristwatch with the high-accuracy atomic clock. When sold new at the beginning of 2019, the system retailed for $2.7 million, so it has increased in value already.
Found it in a science, sci-fi and technology auction year website (https://newatlas.com/2019-auction-science-sci-fi-technology-market/) and had to find a thread! 2nd from bottom of long list!

Why not just connect to THE atomic clock (at NPL) rather than have your own!
TX.
But you'd have to work out how far away from the clock source you are .... hmmm. maybe you could receive a signal from multiple atomic clocks via some sort of global positioning system you could then work out your exact position and the time. Should be accurate enough TX.

Mmm. I'll just use my G-shock that keeps the time by whichever atomic clock it speaks to. I don't need to be accurate to the exact millisecond.
Yes my pro-trek does this as well.These things are accurate to 1 second per 100 million years. I love the fact that they were used to test Einstein's theory of Special and General Relativity.

I once properly understood Einsteins theory of General relativity - for about 10 minutes, and then my brain reverted back to its semi paralysed state and the simplicity and beauty of the whole thing was lost, only to be replaced with confusion, frustration and a recognition that he (and pretty much everyone else) was a lot smarter than me.
Still would not buy one of these monstrosities though - because, you know, I'd then have to buy another so I could leave one at home and then compare them every time I got back from an international business trip.
