HP Caesium atomic watch - BruceH - 08-24-2011
It seems that HP made more than one model of watch - this one being a caesium atomic clock. ;-)

And it has red leds, what nice design!

What...no calendar or stopwatch functions? Those LEDs are hard to see in direct sunlight too.
I predict limited sale success.

Is that an AC power cord entering the back of the instrument, ... er ... watch? I suppose with the other arm or a backpack you could carry a battery and power inverter.

It does have a battery pack.
That allows it to continue running when transporting it to and from calibration as well as during power outages.
I liked the other article on that site about taking a trio of them up to 5400 feet above sea level to verify Einstein's theory about time and space.
