The design of this watch is original from sKander. It is a classic model and has been used in many educational workshops for teaching astronomy, physics and mechanics. It is ideal to be assembled by children from 8 years old to over 100. If you have in mind to organize a workshop, write me to the contact of this site. I would love to participate in your idea.
