Notes

Property of an Important Collector.

Chronoswiss was founded in 1983 by watchmaker Gerd R. Lang in Munich, Germany. Initial watches included the Opus, Tora, skeletonized chronograph, etc. However, it was the regulators which truly defined the brand’s DNA. Its onion watch crown is also a representative signature to Chronoswiss collection.
