Watch enthusiasts agree that each KS watch represents an exceptional standard of horological art that deserves to be identified for posterity. Since KS's early days, the manufacturing numbers of its watches have enabled collectors to confirm their origin and provenance.
In keeping with tradition, the unique production number assigned to each KS watch will testify to the talent and the care its manufacture for generations to come.
The secret signature
Their very success soon made KS's watches a tempting target for counterfeiters. In 1992, KS came up with a countermeasure: the secret signature. Etched into the dial, the signature is all but invisible unless the dial is examined in oblique light. Still a token of authenticity today, the secret signature has remained a feature of most KS dials down to the present.
