Junghans catalog 1923
Although we commenced watch manufacturing at a comparatively recent date our watches have already, owing to their high quality and reliability, gained a world-wide reputation. Our method is: Utmost precision in the production of all parts, ruthless removal and destruction of all parts which are found to be in the least faulty or inexact, assembling, examination and regulation by proved experts. This system ensures equal high quality of all our watches and absolute interchangeability of all parts.
