World's first atomic wristwatch to cost 3,500 pounds

London: The world's first atomic wristwatch - which loses just one second every 1,000 years - could be manufactured within months and cost 3,500 pounds.

A father-of-two from Hawaii is trying to raise 25,000 pounds on crowdfunding site Kickstarter to design the atomic wristwatch, which is the size of a large matchbox.

It contains a laser, a heater, a sealed cavity of caesium gas, a microwave filter, and a photodiode detector, 'Sky News' reported.

The caesium 133 atom vibrates 9,192,631,770 every second, and by monitoring the number of vibrations the time can be accurately told without the need for radio signals or mechanical parts.

John Patterson, who has 10 years' experience in the watch trade, admitted the bulky watch is a niche product that is aimed squarely at technology enthusiasts.

Patterson said if he hits the funding target the first atomic watches will be constructed and sent out by November.
