Screw the iWatch
I want one of these babies. Oo
Could this be the chronometrist’s ultimate timepiece, the peak of horological haute couture? British bespoke movement maker Hoptroff today claimed to have produced the world’s first personal chronometer with an on board atomic clock. The result, says Hoptroff, is a accuracy of 1.5 seconds every 3.15 x 1010 seconds - that’s …
But really - we already have clocks that can set from the radio rime signals and GPS watches - both are already extremely accurate to the point of further accuracy is pretty pointless. I suspect any iWatch would run NTP so it's already going to have sub second accuracy so unless you are using your watch for piloting a cruise missile or high frequency trading etc. I can think of better ways of spending the dosh.
@AC - I fear you are missing the point. The point is that when someone comes up to you and says "Hello peasant, I have an iWatch" you are in a position to retort "Well, that's pretty cool but inside my watch, right now, a high power laser is firing at a radioactive isotope, keeping time accurate to a nanosecond. But yeah, I guess an iWatch is pretty cool as well."
Unless you stick an entirely unnecessary "Nuclear" symbol on the front face
Definitely not flying El Al with that one then.
"Welcome to Tel Aviv, sir. Anything to declare?"
"Only my chutzpah guv."
"Sir, I notice your watch has an atomic symbol on it...?"
"Ah, yes that... Oh no! It's not nuclear, you see what it is is, it's got this gas chamber that..."
"Sir, please step out of the line."
@tabman: Sadly El Reg don't sell them any more as the store has closed. I think searching fr "tritium keyring" might show something up on google though.
@Yet Another Anonymous coward: It was attached to my keys -- even went through US security with it.

Doesn't stop the idiots seeing the word 'atomic' and thinking it could wipe out the city if you dropped it.
The makers might want to learn from NMR, nuclear magnetic resonance imaging. People saw 'nuclear' and got scared, so it was rebranded magnetic resonance imaging (MRI). Same thing, less scary name.
How about 'laser-excited chromometer'?
But then, as I do, she would know the watch was 2 minutes late and realise she can be 2 minutes late.
Then one day, the watch connects to an ntp server, realises it is 2 minutes fast, sets the proper time and then she turns up 2 minutes late for the next 1000 years :)

Er, no. That would be something having that sort of of accuracy, but done with clockwork. In the world of watches your el cheapo quartz job will easily qualify for chronometric accuracy, yet a clockwork one that does will set you back a tidy sum.
When it comes to watch willy-waving it's all about the craftsmanship, not the accuracy. Thus we still have multi-tourbillon watches at the high end of things, purely because they're bloody complicated to make.
You should see the gyroscopic tourbillons, beautiful to behold with the balance wheels rotating on all 3 axis while they regulate the watch, but stupidly expensive (think 7 figures for a watch). Quartz and radio controlled time signals beat mechanical long ago, in the same way that cars beat horses, but people still spend big money on race horses.
