Scientists in Australia have built a watch which is more accurate than any commercial system out there on the planet and is claimed to not lose time for 40 million years. Meet, the Cryogenic Sapphire Oscillator which is one of the most precise clocks ever invented.
Called, Cryogenic Sapphire Oscillator, the system uses 1,200-carat sapphire crystal that is cooled down to minus 267 degrees Celsius, Cnet reported.
It is 1,000 times more precise than any other commercial system currently available and ticks 10 billion times per second. The “cryogenic” in the device’s real name comes from the 1,200-carat sapphire crystal that needs to be cooled to minus 267 degrees Celsius (around 512 degrees Fahrenheit) — only a few degrees above absolute zero.
The prime goal of the Sapphire Clock will be to upgrade the sensitivity of radar signalling in the defence radar network. It will help improve the sensitivity of the network in detecting foreign threats by air or sea by broadcasting signals which are 1,000 times purer than the radar’s current technology.
