180 years ago, a grand vision began on a small scale. With the establishment of his company in Glashütte, Ferdinand Adolph Lange was the first watch manufacturer in the world to introduce the metric system. At the time, this was still a new concept that competed with various regional unit systems. Until then, watchmakers in continental Europe typically used the Paris line, which corresponded to approximately 2.26 millimetres.

At the same time, he developed specialised measuring instruments for practical use in watchmaking. The so-called can micrometer allowed a hitherto unknown precision of 1/100th of a millimetre. In 1851, Lange wrote:
“My first and decisive step was to construct a measure to realise any calculated ratio on the smallest scale with the greatest possible accuracy.”
