back to article Brit horologist hammers out ‘first’ ATOMIC-POWERED watch

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 1000 …

Too right. If you can't use it to attract a metallic boat and thus escape Dr Kananga's alligators, I'm not interested.

Re: Screw the iWatch

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.

Re: Screw the iWatch

@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."

The Quantum SA45s, the timekeeping gubbins of the watch, costs $1,500, so the display mechanicals are costing $48,500

Cesium is not radioactive

Cesium-133, as used in atomic clocks, is not radioactive (and afaik it's not "nuclear material", whatever that is).

Correct. Cesium atomic clocks don't involve radioactivity. Mr. Smith should stop doing drugs while writing for The Register.

"Ah, yes that... Oh no! It's not nuclear, you see what it is is, it's got this gas chamber that..."

About "time"

I so need this. I often worry about turning up to work 0.00001 seconds late.

I bet the battery doesn't last 1000 years though.

Yes, my first thought was battery life. 40mA from a lithium battery, 25 hours with a 1AH coin cell, 200 hours from an 8AH C cell. Definitely not a small watch.

Not radioactive

As caesium atomic clocks use the stable isotope caesium-133, it is not radioactive, and there is no danger of being accused of moving nuclear material while travelling.

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'?

I had a couple of those key-rings, both now sadly defunct. Could El Reg do them again ?

It may be the most accurate watch in the world...

... but it takes half an hour to work out which of the dials is actually telling the time!

Re: It may be the most accurate watch in the world...

And seeing as there are no actual dials there, just the hands, the time you read may well be wildly out anyway!

Yes, yes, I know that the pictures are of the squirkit board and not of a finished product. Get over it.

If you look at the 'front', there appear to be a ring of what look like LEDs, possibly multi-colour, which may work like those in a Solsuno watch, replacing the main hands of the watch. That would be pretty cool.

If I bought this for my wife, she would set it a few minutes fast so she wouldn't be late...

Re: Most accurate watch in the world?

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 :)

Willy-waving.

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.

Re: Willy-waving.

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.

Re: Willy-waving.

You are of course absolutely correct in your assertion. People (males) love their mechanical complication watches. Still you are implying that this atomic watch is not complicated to make, which I guess it is, at least in a miniaturized form.
