The guarantee covers the finished watch and extends to other aspects relating to its reliability such as water resistance (ISO 22810), magnetic resistance (ISO 764), power reserve and performance on the wrist, in conditions representative of modern life.

Exemption from AFM prospectus and permit requirement

Since the Venturist Shareholder Package contains 25 share certificates (representing an investment of € 1,000) we are obliged to show you the following information:
We do not need a license and a prospectus from the regulator for the AFM (Dutch Financial Markets Authority) to issue the certificates. We have an exemption based on the fact that the total value of the certificates remains below € 5,000,000. The AFM therefore does not supervise our share activities. We are obliged to report this by means of the below AFM banner.
