HP Caesium atomic watch Message #1 Posted by BruceH on 24 Aug 2011, 6:11 p.m. It seems that HP made more than one model of watch - this one being a caesium atomic clock. ;-)

Re: HP Caesium atomic watch Message #3 Posted by Mike Morrow on 24 Aug 2011, 8:21 p.m., in response to message #1 by BruceH What...no calendar or stopwatch functions? Those LEDs are hard to see in direct sunlight too. I predict limited sale success.

Re: HP Caesium atomic watch Message #4 Posted by Jim Yohe on 25 Aug 2011, 12:59 a.m., in response to message #1 by BruceH 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. Edited: 25 Aug 2011, 1:00 a.m.

Re: HP Caesium atomic watch Message #5 Posted by Ren on 25 Aug 2011, 1:05 p.m., in response to message #4 by Jim Yohe 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. Ren dona nobis pacem
