INNOVATIONS

The Millionomètre

Jaeger-LeCoultre has always been serious when it comes to precision manufacture. Invented by Mr Antoine LeCoultre as early as 1844, the so-called “Millionomètre” was the first instrument capable of measuring down to a micron’s breadth – a micron being a millionth of a metre.

The Everlasting Clock

Jaeger-LeCoultre’s Atmos carriage clock has seemingly defied the laws of physics since 1928, perpetually tick-tocking without ever needing a re-wind. It comes down to a bellows-style gas chamber, which expands and contracts with variations in air temperature.

The Classic Alarm

The Polaris Memovox of 1968 was not only an exercise in ice-cool dial design but also the culmination of 18 years of alarm-watch innovation at Jaeger-LeCoultre, all based on a hammer repeatedly striking the inside of the case. This technology was first taken beneath the waves in 1959.
