A few months ago, Japan's Shimadzu unveiled the Aether Clock OC 020, an atomic clock based on an optical network of strontium (its chemical symbol SR), and is described as the most accurate clock on Earth, with an error margin of only one second every 10 billion years!

100 times more accurate than atomic clocks! Despite its precision, which may give you the impression that its shape is majestic and huge, the truth is that it is a rectangular structure that resembles a small refrigerator, with a height of about one and a quarter meters, and a volume of 250 liters.

Compared to cesium atomic clocks, the Aether Clock OC 020 outperforms it by 100 times, according to the manufacturer.

Its price is 3.3 million dollars!! Besides its infinite precision, what really sets this watch apart is that it is the first model to be commercially launched, and the manufacturer has already managed to sell the first version at a price of $3.3 million, and hopes to sell 10 units within the next three years, especially to scientific institutions, which takes us to.
