Everyone knows that the most accurate clocks are atomic clocks. And they are located, as a rule, in government agencies. However, soon everyone will have the opportunity to wear such a watch on their wrist. Bathys has unveiled the world's first atomic wristwatch prototype called Cesium 133.
The principle of operation of the watch is exactly the same as that of those that are at the government. Cesium atoms are heated and passed through a vacuum tube, first surrounded by a magnetic and then a microwave field. Microwaves cause atoms to change their energy state. When this happens, they start emitting signals at a specific frequency.
This signal is picked up by an electronic circuit, which processes it and translates it into seconds. Cesium oscillates at 9, 192, 631, 770 cycles per second, which is why the atomic clock is so accurate. In comparison, the quartz crystals used in wristwatches vibrate at 33, 000 cycles per second. The error of an atomic clock is 1 second per thousand years.
The watch is currently 2.3 x 1.9 x 0.9 inches, but the company says it will work to make it smaller. The Cesium 133 won't be a cheap toy, with a starting price of $ 12, 000. Initially, Bathys plans to release only 20 copies.
