History of Telefonbau und Normalzeit:
Telenorma was a German telecommunications and timekeeping company that originated from Telefonbau und Normalzeit (TN). The company was well-known for producing high-quality industrial clocks, telecommunication systems, and public address equipment.  

Founded in the early 20th century, TN specialized in public and industrial clock systems, often seen in train stations, factories, and public buildings across Germany and beyond. Their clocks were designed for durability and accuracy, reflecting the mid-century German engineering standards.

By the 1950s, TN was producing high-quality electric and mechanical clocks, many featuring minimalist Bauhaus-influenced designs. These timepieces were not only functional but also iconic in their aesthetic simplicity, making them highly sought after by collectors and interior designers today.
