Sergey Borisovich Pushkin, born in Moscow in 1925, was the great-grandson of Alexander Alexandrovich, the eldest son of the great poet. After graduation, he came to work in the laboratory of the Central Research Institute of Radio Measurements. Over time, it turned into the Institute of Metrology of Time and Space (VNIIFTRI), and Pushkin's great-great-grandson, starting as an engineer, rose to the post of deputy director.

When Sergey Borisovich headed the institute's time service laboratory, it was she who transmitted through radio stations country time check signals (known as “6 dots”). In 1964, VNIIFTRI began to develop the State primary standard of time, frequency and atomic time scale. In 1967, it was officially approved by the State Standard. The standard was based on quantum mechanical hydrogen generators and a group of high-precision quartz clocks.

All these works were carried out under the guidance of the chief designer of the State Standard of Time and Frequency, Sergei Pushkin. He was also appointed its guardian. The atomic clocks created by Soviet scientists turned out to be a million times more accurate than those based on the rotation of the Earth. Their error — 1 second in 500 thousand years!

Sergei Borisovich has been the keeper of this watch for 30 years. He passed away on July 9, 2015
